I like how this looks.

I'm going to check this one out and see if i like it.


how do you set it up to play the game  i just bought it but don't know how to play it

(Edited 1 time)

Extract with winrar or 7zip and run the .exe also could you tell me what you bought? Because one thing tells you not to buy it.


I-it's not like I played this because I like hentai or anything! B-b-baka!

Anyway, this is actually a really cool game. The character models look great, and it definitely is a cool concept. I'm somewhat surprised that there's even some world building and a skeleton for a plot. I'll be looking forward to the full game~

Last but not least - great job on making this!

I had the chance to play this on my macbook air and its a pretty cool concept, nice job. I can see potential with this game. I enjoyed the adult aspect of the game, obviously.


Played the game today and wanted to know if there is newer release for Mac? Even for an old OS? Really want to see the other characters. I'll check out the patreon page now


The game is not completed yet, it has another year at least of development.

This Demo is very outdated, everything has been improved since then including graphics and even the "scene" itself.

Every girl should have 2 lewd scenes for them for final release, some may have more than 2.

Demo 2 which is a huge build of the game will show many scenes and give a very good idea of what the game will be like will be out before the end of the year publicly for free. 

There is many builds on the creators patreon right now with very good content that you can access for at least 5 dollars.



how do I in zip the file to play?

You use Winrar 7zip or windows 10 built in unzipping system to unzip the file, then you launch the .exe file.


wait for full game


when come full game?

Expected Late 2018, but you could donate atleast 5 dollars to the creators patreon and get access to early builds with some really good content. https://www.patreon.com/monstergirlisland


if so how?<font></font>

Try to disable some AntiVirus program you are runnign. It may think its a virus(Its of cause not.)

(Edited 1 time) (+1)

As soon as possible full :3

we need centaur girl <3


whoa...could you get this working on Android?


very nice. Can you make it work on samsung vr?


When will they finally add a full version?

(Edited 1 time) (+2)

This is a great game and I'm having a lot of fun with it. Also the demon slime Eris is probably my fav charater because she has the same name as me and hot asf and purple. (Thank god I decided not to use my real name for the game because that would've gotten confusing )




Is there going to be an Ophelia lewd scene?




I've downloaded the game but its the small version only with the slime girl... I NEED THAT SHARK IN MY LIFE!!!!! ples tell me how i get the legit version.


never mind i found out bois, time to donate to the patreon :)

how you manage it?

You have to become patreon of this game by donation. They have different versions of this game specifically for patreons only - including the shark girl and many more. Looks like 5$ will do the trick. Visit this: https://www.patreon.com/monstergirlisland

So much time without full game

Man, end July and this game'll be released?  CAN'T  WAIT

Will it really be released at the end of July? Where did you hear that?

how do I get more then just the demo

This game was pretty damn good so far. I got to the ending with slime and the "cliff hanger" I absolutely want more. going to be donating soon to help fund this project because I LOVE it.

it ok so far, but the game keeps crashing and force closing 

Cant get past the first screen where you need to click? doesn't do anything, Help?

<font style="background-color: rgb(245, 242, 240);">

Anyone know when the game will be released??


end July

Wait really? That soon?! I cant wait!

When will the full version be available?

from what I hear at the end of this july

I fucking love this, this is almost exactly what I wanted and looking for, a visual novel combined with exploration elements and open world. I cannot WAIT for updates

The demo is pretty cool, can't wait for final release.

Game: "We all have to eat, regardless of our species."

Me: "Unless you're a robot" *presses space*

Game: "Unless you are a Robot I, guess"

4th wall? What 4th wall? I only see 3 walls and a pile of dust.

HELP! I've messed up the control scheme for the game, and I can't remember what the default ones were, plus I can't find a "reset to defaults" button or anything...any help is appreciated  

Redamz, help me with the crash, with MGI32.zip. When I open the game, I entered the name and loading, the note appear and I dont know how to send the crash file
