Dragons, slimes, giant bugs, centaurs and more. This island is full of monsters and they are all... Oddly attractive!?
From Elves to Kitsune; from Mermaids to Androids; myths and science fiction suddenly become a reality as you find yourself on this mysterious island.
Will you uncover its secrets?
Or perhaps you will attempt to get close to these Monster Girls?

Story and Characters

You wake up on an island.You don't know how you arrived there.
You quickly realize this island is inhabited, but its residents aren't normal people. In fact, they aren't human at all!
As you meet the residents you learn that the mysteries go even further, these monstrous residents find themselves in the same situation as you. They also arrived to this island under strange circumstances, they actually come... From another world!?

During Prologue you'll meet a variety of Monster Girls including a nekomata, mermaid, elves, slime, dragon, kitsune, arachne, and many more!
Even more girls planned for future releases. Look forward to yuki onna, centaur, lamia, tree girl and more!


  • Adventure based gameplay, feel free to explore the island!
  • Fully 3D world and characters.
  • Original Soundtrack
  • Multiple dialogue choices and branching events.
  • Costume Shop (no microtransactions here!)
  • A smartphone with no signal.
  • A good boy that likes apples.
  • A bunch of crabs.
  • And of course, you can get close to the girls.


Prologue features roughly 1/3rd of the main story (individual girl's routes not taken into account). It serves as an introductory, standalone, experience before the final release of the game (that won't be free and won't be finished for a while).

I've been working on Monster Girl Island for 3+ years, it's been a journey, but after much learning and many re-doings I finally think the game is polished enough for the public. What you see here is what you'll get in the full release, for the most part. So please look forward to Monster Girl Island if you enjoy this first part!

Not working...

How long do these links work?

(1 edit)

This is the current discord link

(1 edit)

I need a current discord link please


the dev is a scammer


Indeed. The dev pretty much scammed people at this point


Dev is too busy playing Genshin Impact and working on another project to put actual time into this game. Homie has almost been working on this for a decade and hasn't made much progress. Also won't be many more sex scenes as he finds them "boring as shit to work on." So despite the near million dollars he made on patreon minimal work has been put into this game. Don't expect a full release until 2024 if ever.


Could be thought but, could you make it so when people play they dont get flashbanged when cut scenes change, other than that good game 


Feel like I have seen bits of this game on the internet forever so finally glad to get to play even just some of it. Though feel like I ruined the boob physics juuuust a little bit during my time playing it.

Looking forward to the day it is finally completed, keep it up 👍

I don't have Discord, or better: I can't access it anymore because I don't have that email anymore.

Is there another way to come by the complete game?

I have the prologue for a long time already, and i never realized that there was more; as far as I know, the project was abandoned after the prologue was released.

not exactly abandon, the author is just done releasing updates until the games finished and its not their only ongoing project so no clue when itll be fully released

(Prologue Build only) It's ok I guess. The models look great but the game is too one-sided. As a girl it's kinda boring to play this since you don't really feel like they are talking to you. You can't really choose your character since the answers you can choose are all either rude or just don't have many varieties. You are basically forced to play a perv, who gets bullied by everyone because he can't be respectful and immediately points a crossbow to a girl who didnt do anything wrong(wtf?!)

If that's your character, sure you might like it but that's certainly not a game for everyone.  4/10

(I'm going to try the finished game which is on discord. Perhaps it's better.)


Friendly reminder that anyone can false copyright claim his game on steam to get this piece of shit doxxed. Maybe that will put some motivation into his body! Simply open a claim with steam, hand them wrong contact details, fake company etc. and they will be forced to hand you over his actual details. It would be interesting to see if he paid his taxes accordingly, considering that he made so much money through crowdfunding...

the discord had an update posted back in May. dont blame the author cause you dont know where to look.

Deleted 23 days ago

Where can I find the update?



Except it hasn't mate. He's working on another project while playing games and doesn't actually care about the project. Swindling people out of money at this point

more up to date version than whats available here.  updated scenes, dialog, ect along with 2 additional scenes not in this sites version.


Will there be more updates?


prob not, the dev is lazy af


updates have been posted on an discord group




is there any new updates?

The zip file doesn't download for me

Your game ( monster girl island) looks amazing! Can I make a video playing it? I will add where it can be bought ^^(knowing that I post it on porn website and get some ad revenue from my videos) thanks for reading me! 


I personally return to this game every few months -- not because I hope it's done, but because it inspired me to work on games of my own. My work is nowhere near this level, but I sincerely hope that - at some point, this game is finally released / completed.

You make a cuck game with zero actual Monster girls. Lol no

Oh no, a "bad" comment from a random  rude person on the internet - that's never happened to me before. What ever will I do? 
My day is "totally" ruined. 


yo you gonna make an apdate? because i love the game


Any way to play on fullscreen?


Alt F4


maybe alt + enter




Guys, there are updates, and they are free, just join the discord


link please


Deleted cuz posted the wrone one


Bro, if you do not mind throwing an invitation to the server, as soon as I enter does not take :/


that's literally the invitation


dev sucks


Gameplay traduzindo para português do Brasil :)

actually nuts you havent had an update since 2019 being that it is almost 2023. I get that you want to just work on it but 3-4 years with no content or updates is actually insane when its buggy, slow and hardly has about 4-5 hours of content AT MOST due to the pretty lazy currency system


tbf it's free and it's his game so he can do anything with it


tbf i didnt ask, and no updates is a one way ticket to everyone forgetting about you


and if people forgetting you so what? and i seeing a lot of people coming here, even i got 8 downvote, me make me think they still remember him


As soon as he received crowd funding he became obligated to make the game that his patrons were promised


Quick, developer, take time out of your life to get an update to this free game out so this guy can rub one out! He is clearly more important than what ever you have going on!!

People are rightfully angry with this dev.
For a point of reference, he generated almost 3 million dollars a year from this game at one point via Patreon.
It's been nearly 4 years since any kind of *substantial* update.

I can sort of understand their anger.


me when i lick the boot of a creator that gives no shit about the people giving money


Way more effort put into this than the contemporaries, solid game props to the dev hope he releases the final version sooner than later, but you cant rush a good product.


fuck the developer




Is this game canceled?

Deleted 75 days ago

so oficially he stop uploading updates to public, and he will just put off whole game at once when he done 


The Mysterious Endgame

For anyone still waiting on the full version of this game you should know that the dev has admitted on discord that in all the time spent working since it's last update he has not made any new lewd scenes. He says they are "boring as shit to make" and that the final game will probably only have a "couple" of new scenes. So don't get your hopes up if that's what you're looking for, only look forward to this project if you are solely in it for the story (as ironic as that sounds).

can u inv to discord?


The funny thing is to see some people defending the creator. You see, if you make a game and it takes a while to update, what's the first thing you should do? Inform. Release Peaks to payers and then release to the public. But the creator doesn't even do that — anyone who defends it and still waits for a future update is stupid.


Same thing with the Summertime Saga
there a big division in the discord and mods are purging anyone that dares speak about the long time

Deleted 57 days ago

When you know how to interpret and realize that I quoted people who pay patreon waiting for updates, you will make a reasoned criticism in the next one.


Retard, you aint even looking for updates, last update was a year ago, he posted it in the discord for free, there are like 4 more sex scenes


With this baseless criticism you should just be friends with the creator sucking his ass, I won't even argue. When you have a good idea why — even those who pay patreon — don't get the necessary information about the game. Also, whoever asks is literally removed from the server.


poor kid got removed and is making a tantrum, that's all it was about at the end, just sad


idiot. You definitely sucking his ass.


A toast to all the idiots who actually supported this game! A toast to all delusional losers who are still waiting for it to come out! A toast to that bastard “developer”!


stfu bro just wait for the full game

why the heck is the graphic set so high that even the title screen crashes my whole computer, compared to when i can easily play the '(old)' version easily without anything crashing?!


Feel ya the game was smoother back then not sure why it's so laggy now I hope they fix this issue or at least automatically make it that the graphics are low when you start the game 


When Was the Prologue Put out


dead game




hello every body i have a question i was on discord and my account was hack and i cant joined this discord anymore and there was a few discord i cant join too does some no how to help out 


I don't know why people keep complaining and scolding the creator, it was clearly stated that this is the prologue and it was 3 year of work and it is free. But there won't be update until the final version of the game is done, which will be paid. So if the prologue only needed 3 year I can imagine the full game will be twice or thrice of that time. Let's just wait and act like intelligent human beings.

(1 edit) (+26)(-3)

The complaining and scolding is a result of lack of communication between developer and supporters. There has been no visible* progress of the game in a year+

(1 edit) (+8)(-25)

Did you ever thought about him being bored about all those when/where questions and thats why he doesn't answer? It was clearly stated that there won't be any more update for this cuz he is working on the full game, which is not 1-2 year to make. Even an experienced big studio is working on a game for 5+ years and however this game is by far not that big BUT THERE IS ONLY 1 PERSON HERE. So think about it and read carefully what he said before complaining. People should learn to read the ingame notifications and patreon/discord/website ones of a developer before scolding and asking stupid questions.


theres also a slight chance that he mightve gotten bored with the project and he is just racking up the money

(2 edits) (+12)

I frequently see myself visiting this games page on Itch or Steam to see if its been updated. Unfortunately it has not. This game is fucking amazing and I hate to see that's it dead. I wish the dev would communicate on what's going on or at least explain why it hasn't been updated. I understand the fact that if hundreds of people are pressuring you because they want something, it can be very annoying. However, this wouldn't be happening if there was more clarity. Anyone seeing this game for the first time should try it out because it is great, but expect to be disappointed when it ends right as its starts to get interesting.


scummy dev


bans fans for asking about th egame, keeps the money. dont suport any of thier projects if youre smart


I don't know if you know this but go on his discord he has patreon version on their for free cause he got banned on patreon and he bans people cause people keep asking so leave him alone, he said it was 70% done


More like abandon than done.


Waited three years for an update and I do NOT regret cancelling my sub after on month of no news. Dead game, no updates. You also get banned from the discord for asking.

is there anything to do at least?


It's a pretty fun game for what's there, just don't pay money for it. 


There was no obligation to pay for this. You did that on your own accord.


I wish him good luck buy i feel sorry for the paying fans that waited years


Latest Update is 3 years ago.... 😂
