So Is There Any Sex In This Or............

I wrote about Monster Girl Island along with some others in a Valentine's Day post on my blog here: http://pajamagaming.blogspot.com/2017/02/happy-val...

Looking forward to seeing this as a finished game!


I pledged $15 to your Patreon. Do I get a cookie?

(Edited 1 time) (+1)

I downloaded the game on mac but I can't figure out how to fish for fish in the starting and its not allowing me to skip. Unfortunately, thats as far as I have been able to get to. Is there anyway that you could tell me how to do that.

fyi; https://www.patreon.com/monstergirlisland/posts


So users who donated here can get the new patreon demo? or will i have to pledge 5$ on patreon? cause i paid 5$ here but pledge 1$.

I have an advice for people, want to know the news of this game? hit the "Website" link above the "Patreon" and browse on that page, it is updated (somewhat) regularly.

What website? monstergirlisland.com? Cause that's where i download mine...

That one, since from a time now i have noticed that some of people that post here have outdated info or have no knowledge of the progress being made.

I have a question... After the game is finished... Will it be free or do we have to pay for it(or it is depends if we wanted to?)? Because if i have to pay for it i'll just keep play on the demo T^T. If its free that'll be so damn awesome. But im not begging for you guys to make it free. Just asking...

Thanks for the game! It is reaaaally AWESOME!


Hello Redamz, i want to ask you a question. Is the game is still at demo (i tested it with the slime girl scene, but there no more) ? If no, how can i download the latest update ?

(Edited 2 times)

He has a page (in tumblr i think) where he keeps showing the (somewhat) progress and yes, as far as i have seen this thing (is not exactly a game, not a date simulator nor a visual or interactive novel so far) is still a demo, apparently (sometime) on the future he will finish demo 2 which will (apparently) will be (way) different from this.

This might be a demo for several reasons like:
Not having all the girls completed
Not having the scenario (the story) completed
Not having the whole island completed
Having to adapt the whole thing to VR
A mix of the ones above and that (apparently) he is doing it all alone.

P.S.: The dude is also trying to improve the game yet keeping it as it is so those who could play on the demo 1 can keep playing the demo 2

Oh, i did'nt know, thanks to the awnser.

i purchase the download through this site and was wondering if this is the same as being a patreon? i donate $5 when it asked me if i would like to donate.


i bought the patreon pack here a long while ago befor it was outdated and i was wondering if ill be able to get the new content?

Hello I have a question. I brought the game here so how do I get the newer versions? Is this archive are gona be updated?

Hello, Thanks

I want to ask a question,what's the meaning of "outdated/don't buy?"If I spend 5dollars,I won't get the Patreon pack?

You will but that pack is missing the latest build.

You should get it on Patreon that accepts paypal now.

I'm still gonna upload public demos and sell the finished product here but since there's no way to add stuff to the existing pack it's kind of a hassle to keep it updated here on itch.io

And how do i get it trough Patreon? I'm sorry i'm kinda new to this.

Just a question since I did pay the 5 dollars here.. Do I have to pay it again on the patrons page to get the latest update?

I'm downloading an indie game featuring monstrosities with big heaving boobies and that is in no way sad.

My life is awesome.

I'm unable to download the game. After I click download it goes for a little then it just stops. I'm trying to download the Win32 version.


how get full game


Any update on the game? Just out of pure curiosity.. And research... Hue hue hue...

Apparently, people who downloaded your game also went to go download mine, so thanks for the unintentional referrals :P still up to help you out with this game if you need it sometime man! :)

Thanks man!
About referals, yeah they are very helpul. I get a lot of referals from other H-games on itch.io too.

Well I have to say this game is something I wasn't expecting it to turn out to be. When I saw 18+ I was expecting a few pictures here and there. But what I saw was amazing! I won't spoil it here, but sir and or madam please continue this game!


Probably not a good idea to upload that kind of uncensored gameplay on youtube :p
And thanks!

the installation for the game is a little tricky on linux platforms if you could make a instalklation guide or something thatd be nice

This game is amazing!!!

I can not wait for the full version.

Do you accept proposals for new girls?

how much will it be and how can i buy it?

any specific realese date? I want to test out how many girls my stamina will get me through

Less than one

Ummm can i pay with paysafecard ? i extra buyed it to buy this game :C

I'm having a problem progressing the demo. When I've gathered the 3 ingredients, I could only give the fish to Ara. If I try to give her the crab and the coconut, she just doesn't take them.

You need a regular fish to progress, not a rare one.

Figured :D Thanks, great work :)


When is the demo 2 being released?

anyway demo 2 release?

This game is freaking AWESOME! I had waited for so long to be able to buy the newest content using paypal. Thanks Redamz for great work. ^_^

Is this demo's the only one I can get? Or should I required to be the pateon to get further? I really want to know how can I get a full version.

I am having the same issue ... I brought it but the game shut's down after the slime girl

That's not an issue, that's just where the demo ends.

(Edited 1 time)

Where is the folder save of MGI? (i want chane PC but don't want play again ||_|| )

(Edited 1 time) (+1)

The save of demo 1 is useless for future versions but it's stored in users/(your user)/AppData/LocalLow/by redamz

Hey Redamz , Rlly great job dude! Anyway , You have a date to next demo or full Game? Can't wait Waaaah D:

I can't wait ether i just got the demo last night.

are you going to be able to use a controller with the full version or later on?


I don't think so, the game uses mouse cursor too extensively and I don't think the time investment of adding some awkward controller support is worth it considering the game is designed to be playable with one hand in lewd scenes.

Maybe I'll add support for VR controllers though.

thank you for answering my question and i guess i'll have to make do with what i have.

So much potential for VR \o/

Really well executed. Hoping to see a full version soon.

I don't have access to a Rift or a Vive but I tried some scenes on Gear VR and yes, it works pretty great.

Don't expect full version too soon though...

Has the demo been updated yet or does it still end with the Slime girl scene?

No new demo yet, only a couple extra lewd scenes on patreon (that will be part of demo 2).


AMAZING! Seriously, this game is incredible and you are doing a great job. More people need to know of this because seriously, you are doing so good, it deserves to be noticed. A few grammar mistakes here and there but that didn't really matter. Some animations need a little more polishing but who cares! Keep working on this game, try crowd funding, anything! This needs to happen. I'd give a couple hundred to this if I could because this game could be really, really big. If you are ever looking for writers or anything like that, I have done a lot of things in different areas. Anyway, the point is you're doing an amazing job. Keep it up! :D

Thanks man!

I don't think I need crowdfunding beyond Patreon. I'm doing fine.

Maybe if people want something fancy like multi language VA I'll throw a sneaky indiegogo before release but otherwise is not needed.

Not a problem!

Your Patreon seems to be doing well, I'm really glad it is as well. You deserve all the money you make.

Hopefully you hit the point in which you can get some decent voice actresses and things, that'd just be the icing on the cake really. Anyway, thanks for the response, keep up the great work and I hope to see as much progress as possible as soon as you can. See ya, and good luck.

btw, is this game going to be on steam when it releases?

It's possible that I put a censored version there AFTER release.

and make people pay for nudity? that's smart, anyway, if it is on steam I will definately buy it

(Edited 1 time)

I would donate you money if I could Redamz, great work


Yo! Redamz-san so you said if ever confronted with a Problem we'll send a crash-log right?! so where would I send it...I fully supprot you but I can't financially support you yet, due to reasons...so Please continue what you need to do


And no worries!
