Will there ever be mac version for this? It looks like a really cool game.

Hi Kazuhira,

I’d like to support Mac & Linux on Vulkan  one day.

I will try to make a stable Mac build when I get to beta.  That is likely early 2021 at this rate

Kind regards,


Hey i have a problem when i press ''New Game'' im just stuck at the customize your character it doent even show the ''New Game'' Anymore

Sorry for my bad grammar

There was a similar issue like that a while ago when not using a 16:9 or 16:10 screen resolution in Window Mode.

Try running it on full screen mode.  If that doesn't help could you send me a screenshot so I can work out what's happening?

Kind regards,

Can I ask you to change something?

Hi DarkNix,

I’m always open to feedback.  Let me hear your idea.

Kind regards,


Can you change the walking motion?

Hi DarkNix,

This is a common request.  I am waiting on a new male character model with better proportions that will solve this issue.
I didn't want to waste time on the placeholder male model.

I'll get a quote from an artist and see what can be done about the current model.

Kind regards,

Dude, why theres names in trees?


Hi Samurasa,

Patrons & subscribers pay for the privilege of being immortalised in the game world.  Their names appear in trees, statues, plaques and soon fountains.

It’s a way to thank my supporters for their generous contributions and making it possible for me to make this game.

Kind regards,


Hello Hunter,

0.30.2 has been released and it has the fix for the critical bug where you cannot start the game if you are playing in Windowed mode.

Kind regards,

I grabbed the alpha 0.29.3 and when I start a new game, I can customize my guy but there is no way to proceed.

Make sure you enter a name or Click the Random button to randomly generate a name before clicking OK button.

When playing in windowed mode (on my Windows laptop) the menu isn't in the box. Additionally, when creating a new character, the options were similarly misaligned, I couldn't change the hair type, and there were no buttons for picking a name or moving forward.

Changing to fullscreen resolved most of the issues. However, I couldn't enter a name. I was able to move forward with the game, however so maybe I just couldn't see the name being entered.

Previous versions were great, but people might get turned off too early if the character creation part is bugged. Good luck though! I'm excited to see where this goes!


Thanks for reporting this, mate.   Nice troubleshooting.

I have fixed the issue and it will be available in the next Patreon Release.
However, I will have a fix the current version in the next day or two.  Retrofitting the fix into an older version is fiddly :)

Kind regards,

Thank you very much! If the next version has the fix, then that's the most important part. If you can fix the current version, that's great, but not as essential.

Again, thanks for making this game! I'm looking forward to the next version!

This is an introduced bug.  A fix will be available soon.

Thanks for reporting it.

Kind regards,

im sorry but where is the beast?


The beast is a big part of the plot and is coming later.

I’m working on some of the more technical items in the game at the moment.  I’ll add more story/plot later.

Kind regards,


Love the game so far!

Question, is Natsu's progression implemented? I have 100% on everyone else, but Natsu shows 5 levels in the journal. And I can't find any way to interact with her other than her hinting the village is supposed to be there. I  have checked the whole map several times and can't find any more items.

Hi Clara_Krieg,

I’m glad you’re enjoying the game.

I’m afraid that’s all she does in this version.  A bug in the current version shows more than  one relationship  circle.

This has been fixed in the latest Patreon version

Kind regards,


thanks for the heads up :)

How do I get to the bunny girl?

Nice game btw

(1 edit) (+2)

Thanks, mate.  It’s shaping up nicely.

To find Natsu you’ll need to run past the pond and follow the canyon to Greenfen Forest.

Then take the path to the village.

Kind regards,


could you please help me i have a black screen  when i start the game  v

MonsterGirlTailesv0_27_0 64bit.zip476 MB

Sorry to hear it.  Usually this is caused by antivirus software removing some core files required by the game engine.

Try this:

  • Disable your antivirus temporarily - usually a right click menu from the system tray
  • Extract the zip file again 
  • Run the file "Monster Girl Tailes 64-bit.exe"

NOTE: Don't forge to re-enable your antivirus software afterwards.

It may also be your zip software.  Using something free like WinRAR or 7-zip should be fine.
Sometimes the inbuilt Windows extracter doesn't work so well.

Kind regards,



i am gay

On the catgirl's "milk" scene, her breasts are off-kilter (one is significantly higher than the other on her frame).  Played with camera rotation to see if it was just the angle I was looking from, nope, it was the model.  Possible its just me, but in case it isn't, figured I'd mention it.

(1 edit)

Thanks baltham,

You’re  right about the breast position.

it’s a minor bug with the breast physics.  I just have to modify the arm position 


After talking to Natsu the journl breaks. It only shows hair and outfits of the girls and sometimes the wrong ones. Other than that, it's a great start and I'm excited to see where it goes.


Do you mind sharing a bit of your tech stack for this? What did you use to make the models/animations? Are they variants from a set of prefabs or did you work from scratch in blender or something? I love the look of this game.

Hi Black Finch,

I bought the original models from the Unity Asset Store and then hired artists to make heavy modifications.  Tools used varied by contractor, but mainly Blender and Maya.

I then use my custom mesh combiner to assemble the characters with hair, body proportions, clothing, etc.  The mesh combiner also rigs the skeleton accordingly.

I would recommend making your own character models instead of buying assets if you have the ability.  It makes for a more unique looking game and is a fraction of the cost/effort.I’ll never do it this way again :) 

Kind regards,


Heyya :)

This game is pretty neat as far as it is, the models and world have potential.

There are two things I'd love to see, or to know how to archive if already implemented:

1) A continue button. I was very confused that I saved and couldn't continue the game. Took me a while and a couple times of replaying the beginning until I realized, I could save, exit the game, open the game again, start a NEW game and do a quick load from there. 

2) a positional reset. Either to a fixed point I lately came across or - to keep things simple - to the starting position of the game. As of right now I'm stuck due to a bug while an H-Scene. Suddenly map and female Character disappeared, leaving me with a sky and the protagonist. As the protagonist looks up all the time, I could only guess, that I got below the map and I can't see it from below because the areas are rendered from one side only.

As the concept is a nice one and I really like the models and the small-but-open-world style the game has, I'll closely watch how the game develops :) Keep up the good work!

Hi DevyLost,

I'm glad you enjoyed the alpha so far.  

1) A "Continue" button for the main menu is coming.  I am sorting out some bugs with loading of the game directly from the menu at the moment.
2) Rather than add a reset position feature I'd rather just fix the bug.  Which H scene is it you are having issues with?  Which girl?

You can look forward to some more open levels and more characters in the not too distant future.

Kind regards,

(1 edit)

Hey iLEWD, 

thats great news :D

About the bug:

It appeared right at the beginning of the H-Scene with the feline sword-wielding girl at the small bridge, schould be Misato. It's the first/only H-Scene with her. I think the time was set to day. Got a sword, Ice cream and Head band in inventory. I guess I got myself a new map already. I also asked Himeko for a sword again and she gave me one, game showed the gain message but there was still only one sword in the inventory. Not sure if that could have something to do with the bug, but is the only 'outside the box behavior' I could think of, that I did in the game before that bug.

The bug itself:

After the last line of dialogue, the Protagonist and Girl should change position for the H-Scene to happen. Protagonist does just that - and goes through the whole scene, given his lack of clothes and his movement. But all alone - the girl was gone and with her the whole map. All to be seen is the sky and a dark blue abyss beneath the protagonist. After what is probably the length of the scene the protagonist turned back to clothed and upright standing. I can't move him, can't even trigger the walk/run animation. I can get into the inventory, change the time, open the menu. So all the keyboard reactions are fine, including save and load. Cameramovement is fine too, can look in all directions, right up and right down.

Beside that bug:

Hope that (lengthy) description will help to track the bug down. Do you have some kind of public bug-list, where people could submit bugs and look up what bugs are submitted already? I personally hesitate to submit on, say itch comment section or similar, minor bugs, that probably someone already told you about, maybe even 30 times. Having a list I could go through and only add a new bug if it's not already listed would be neat.

Best regards,
Devy Lost

i have very high hopes for this game but i will say there is a lot of bugs. although i did have a fun time. am i supposed to know how to use the dev tools? and there is a bug with that, if you up the relationship at all with any girl you can never talk to them again 

I’m glad you enjoyed the game. It is still in alpha, but I have tried to put enough in the game that it is possible to see the potential of what the finished game could be.  The bugs will be fixed one by one as I go.

The dev tools are just for me when testing the game.  They’re no intended for players so there are side effects like you mentioned.  You can use them if you like, but you use at your own risk :)


I have been questioning myself, about the catgirl with green hair behind the "house" what should i do with her? i gave her some kind of "ball" but i don't know what to do next: / and yea, your game is very good! just need to fix some bugs and fix a few characters movements and clothes ... in reality, have to fix a lot of things, yet still waiting to see how it will be when you end the creation of this art we call game. i loved it  :)


Akeno, the cat girl, is hungry.  Ask yourself what cats like to eat.  Maybe have a look around the pond.

If you get stuck again you could ask the community for hints in Discord https://discordapp.com/invite/xwm73bN

Thanks for the high praise.  I’m currently working with 3D artists to rework the girls including boob sizes, genitals and clothing.  Hopefully I can put the new models in the game by Christmas and then I can fix some of those pesky bugs.

I was surprised by how much fun this game is. It reminds me of Rune Factory for the Wii with its style, which is a big compliment. 

Beautiful game! Keep up the great work while we look forward to everything ^^/)

A lot of potential for this one. I wish the dialogue choices were'nt via mass effect style. Is giving the map to the guy a trick? Do I need it for the Elf? Does the nekomata behind the school not want the ice cream from the campsite?

Woah.  That’s a lot of questions.  First, the Mass Effect dialogue will disappear on the next build.  Let answer your questions without giving too much away

  • No
  • No
  • Yes

Damn I wish I can play in phone._.,

After returning to the main area from visiting the bunnygirl, I fell through the map as it was loading...

Guess I should've slowed down a bit.

There is a loading bug that I am working on right now, but it's proving to be very tricky

lol something you should know then... the blue platform thing in between the main area and the bunny area, if you quick save there and reload, it breaks the game. not only can you not move, it says "load failed" or something like that, as well as making it so that if you go to the main menu, and start a new game, you cannot talk to anyone, or interact with any items. just some useful intel. awesome game, thanks for figuring out the zip file issue, now that I can play it, it is great. Excited for updates!

Hey there, I'm getting a corrupted zip file error when I try to install...? :(

I'm using the x64 bit version.

Make sure to down part 1 and part 2 zip files.  It’s a multipart zip file you’ll have to download from the web page, not the itch.io launcher.

I've solved the problem with the multi-part zip files.  Please download and try again.

Hey there and thank you, I'll give it a go!

Is it possible to play as a girl?

(1 edit) (+1)

Sorry, Jeffff.  I’ve had to rule out playing as a girl or futanari.

You can read more about it here.

Kind regards,


Link is broken. Brings me to here Technology.


Thanks for bringing this to my attention.  The link is fixed now.

the game seems to keep crashing when i enter my name in new game 

This is the first time I’ve heard of this.

I’ll check the crash logs, but it’ll help me figure out the problem if you tell me a few things:

  1. Game version
  2. 32-bit or 64-bit
  3. RAM
  4. Video card

I'm having the same problem, 64-bit 8 gigs of ram nvidia 750 ti

Hi! This looks like an awesome game, great work in the development. Recently I tried to download the 32-bit version and I receive a data error on unzipping. should I be using different software?


It’s a standard zip so your software should be fine.

Just make sure to down part 1 and part 2 zip files.  It’s a multipart zip file you’ll have to download from the web page, not the itch.io launcher.

(2 edits)

Thanks, I made the mistake of only trying to unzip the one without the other, it's unfortunate though that I have to wait till I get some better graphics, my onboard is only 358mb, game doesn't load or loads very slow, although, I played another Unity game recently and It ran fairly smooth. I have 4GB Ram, a Duo Core. After testing against Task manager when running, I Found the game drains all of the RAM slowly, it just climbs higher and doesn't stop till it's using 100% when loading from choosing a name. it is designed to go over 1,000,000 K?

I have not observed the RAM gobling issue myself, but I'll take a closer look.

I have not yet done an optimisation pass on the game so I'm not surprised it runs poorly on low spec PCs.
The good news is that the new female models, materials and textures will drastically reduce the size of the project and the required memory.

The dialogue selection menu in the trailer looks VERY similar
to the one in  Mass Effect 1


That has been replaced in the latest version.  Although I still need to replace all the screenshots :)

The game is no longer compatible with the itch client app.

The app requires a single downloadable archive file for the game. Splitting the archive into two parts (.ZIP and .Z01) breaks the itch client. (Though maybe there is a way to get itch.io to consider the two files to be one release.)

Hi Formedras,

I hadn’t considered the itch.io client!  That explains the recently reported issues.

Looks like I have some work to do.  Thanks for the tip.


You're welcome. I also sent an error report to itch, asking to support multipart archives.

Thanks, but I used a multipart zip file to get around itch.io max file size of 1GB.
It would be more usefull if they allowed for at least 1.5GB zip files.

(1 edit)

I download the right version for my 64bit PC, but I cant run it???

However I was able o run the .18 version?

Send help? (I extracted the files, but the .exe wouldnt load anything)


But I cant feed the girl near the building a milkshake I have?

Maybe she is not in the mood for a sundae just yet.  What else do cat girls like to eat do you think ?

ive gotta say this looks very interesting

i hope it's good


I cant download the game on the launcher and when i try and get the game on the site it says the folder is empty whats going on?

This is my fault.  The latest builds are in a multi-part zip file.  Turns out that the itch.io client launcher does not like that.

Go to the itch.io website and download both files.

I'm working on a permanent fix for this.

why i can't click the new game button to start the game???

(1 edit)

Hi perryng123,

This was discovered recently.  It has to do with large resolutions.

Try 1920 x 1080 and it should work.  I should have a fix for the next version.

Alternatively you could try using the arrow keys to select the New Game button and press Enter.

Played this game back when it was .0.5.0 Must say that I am overjoyed with the progress you've made, but for some reason I can't interact with anything after downloading latest version.

Hi Rpitsy22,

If you have not played for a while I think you're in for a real treat.

You should be able to interact with characters and items by walking up to them and facing them directly.  If they are in range then you will see an icon appear above their head.
Then just press E and you're interacting.  Hooray!

If that does not work be sure to check that your antivirus has not annoyingly removed some game files.
If it has then disable your antivirus , unzip the files again then launch.

If you still have trouble email me some screenshots at interlewdcreations@outlook.com and I'll get you going.

Good luck, hunter.

Kind regards,

I look forward to what you have to bring in the future for this game and from a player's perspective am impressed with the quality of it so far. I have a few questions.

I especially enjoy the music in your current version. If it is ok, where can I download/listen to the song?

I would really like the option of having a first person view both while walking around in the world as well as scenes. May I suggest this if this has not already been?

Hi 2patient,

The music I am using is a temporary track until I can hire a composer.
You can find the track here

I am currently exploring adding first person camera as an option.  A lot of patrons have requested the ability to get upskirt camera angles.

Kind regards,

You should consider sending Steam a demo of your game and seeing if they allow it. They allow games like this now. Then start up a Kickstarter campaign to raise funds so you can work on it (keep all rewards digital). Steam and Kickstarter allowed this game,   https://www.kickstarter.com/projects/990500595/subverse/ which is made by this company https://studiofow.com/. I see no reason why they wouldnt allow yours. Really consider this please, this game has the same potential. Currently the game is up to $1,703,617 USD with 46,020 backers.


Hi FlyingBlind,

Thanks for your enthusiasm.

The success of the Subverse Kickstarter campaign is encouraging for adult games.  When I started making MGT I ruled out Kickstarter because back then I was a small fish with no real experience and I didn't think I could run a successful campaign.

It's very tempting to try Kickstarter now, but I have to think about those who have already pledged on Patreon.  I need to find a way to be fair to them if I also raised money from Kickstarter.

It's something I'll will have to think about very carefully.

Kind regards,


Would love to see you try it. Maybe get all your patreons  emails and allow them to create an outfit for a character, names in a special thank-you area in credits, free steam key and maybe mail them a signed poster of all the characters or something like that if you ever do a kickstarter, Look forward to seeing the future of this game.

Probably one of the most promising game I've played so far. Of course for the instant the game is still pretty light, but I trust the dev, the game is going to be really enjoyable. By the way, I think it would be an improvement to translate to other languages (or let the community do it :p). Anyway, keep up the good work, cannot wait to see the next version !

(1 edit) (-1)

You should check out subverse.     https://www.kickstarter.com/projects/990500595/subverse/ 

Hi Freeaccess

Thank you for the high praise.

Much more to come.  I am working with many artists at the moment and translation is certain on my radar.

Kind regards,

Bug Report:

There is an Inventory glitch, I was trying to mix items to combine, but it froze with one item in the combine field while I tried to exit. Also you didn't set flags for items, so you can keep getting swords and maps. There is a bones pose error on the Teacher. The graphics do glitch, which might be way someone else reported their computer heated up. You cannot scroll on the Journal screen to see other characters in the list.

Other then that, not bad for a demo.

Hi jomeijackson.  Thanks for the bug report.  These are  useful.

1. This combine items issue is a new one.  I'll investigate further. 
2. I am working on the Dialogue System to use flags, but it is currently under-featured.  However, the Inventory System is clever enough to know not to add duplicates.
3. I'm currently trying to solve some pose issues in H scenes where arms and legs do things they really shouldn't :)
4. Not sure what you mean by "graphics do glitch".  Can you be more specific?

The game is not yet optimised so some lower end computers can struggle.

Kind regards,

(1 edit)

1. Just try random objects, it froze when I used the map and the hair band.

3. That's a skeletal issue in the pose, some how the axis is messed up on the teacher's pose. Did you create the assets or get them from the store?

4. The reflections sometimes vanish and I can see through certain objects.

Got stuck at a few parts (I think its just the end of the demo) but every minute I played, I enjoyed.

Well done and I can't wait for updates.

I’m so glad you enjoyed it.

I still have to add the hint system & remove the boulders, but the Completion percentage should 100% if you have spoken to all the characters.

Update coming tomorrow ;)

awesome cant wait for new version

Thanks so much.  I was so proud of the last release.

Next version should be out in a couple of weeks.
