It's a 3d adult game with an anime-inspired artstyle, featuring monster girls as the main focus. The gameplay is divided into "story mode" and "free roam". The story mode, as the name implies, consists in progressing through the story, getting to know the main girls and unveiling the mysteries of the island. Most of this in VN-like fashion. You can always leave the story for later and focus on doing whatever you want. Flirting with the girls, Obtaining new items, customization(eventually) and even finding new monster girls through the island. It's your call.​

2023-06-13 Added MGI Builds in Unique Builds v0.44.3 v0.41.3 The first half of Chapter 4 Prologue v3.5.1 Many, many, many bug fixes. Added more events indicators and other hints in parts where players got stuck. Some animation improvements. Improved collisions on the village and lake (you can swim at lake now) Autosaves added. They aren't a replacement for regular saves, just an insurance in case you forgot to save or got a crash. The game autosaves when you enter a new area and after major story events. A new ending was added. The game continues for a bit after the Ara/Shuri conversation, you can now experience the start of chapter 4 which serves as the final closure of Prologue. Day 3 Here's day 3 of the story. A remake of the original demo, plus quite a few new scenes. Please note that this build doesn't have any new lewd scenes, but it gives context and places into the story previous ones. Some notes: The new part of the town is unfinished, those colored rectangles forming a circle will eventually be flowers. F1 for graphical settings, they are saved now and loaded automatically for all your playthroughs If you see black, glitchy spots in your screen , disable HDR in graphical settings. Work left for prologue includes making a bunch of new items, animating a wolf mount to travel faster and adding tutorials, better save management for the user and general polishing. After that's released it'll be all lewd scenes for a while. Day 2 As for new mechanics: You can buy, sell and craft items at different shops. The inventory is not large at the moment but you can test all the mechanics with the few items there are. New inventory system. Right click to use. If one of your items has an active effect you can click it and hit the "use" button. You can hunt bugs and fish with a spear. The bugs have no use as of nw besides looking pretty in your inventory. Instead of inner monologues, Ophelia gives you a call to describe objects you interact with. During lewd scenes where you can click or hold to make the player move you can now press f1 for auto-mode. If it's a click to move scene then the automatic speed will depend on the time interval between your 2 last clicks. You can get phone calls. Maybe you'll be able to make calls in the future, still undecided. Dialog system now works the same in VR and non VR versions becuse it was a pain in the ass for me before. Buff system. So far there's only some dishes that last 10 real life minutes and give you speed. Effects that didn't make it to this build include higher chance to find resources and increased money gain. Known bugs: Don't save and load when Renge walks towards the bridge at 9pm. Unless you want to miss her scene that is. There's probably tons of ways to go out of bounds in the forest. Please do report. There's likely a ton of typos. Time is permanently frozen after Renge's scene. Save/load should fix it, but there's not much to do after that scene anyway. Random stuff: Some QoL improvements to Mako scene and the pushup animation looks less retarded now. There are not locked options anymore. Also looks prettier. Otherwise it's the same. Skip the new scene if you are not into anal, sorry. You start with 500c (money). Because I didn't have time to add any quests that give you money, so otherwise your only option is to sell stuff you find. I'll send the message with the definitive build once I fix any bugs people might find. Grass disabled by default, press f5 to enable. Day 1 Now onto this build: This is roughly 1/4 of demo 2 (Or not really, since day 4 will have 3 scenes in comparison to the 1-2 scenes of the other days). I don't know how the length of this build compares to demo 1 (since at this point I'm godly at speedrunning it) but content wise it's way bigger. The performance might be bad if you have an older PC since I couldn't optimize everything I would have liked, so sorry about that! I'll try to upload a revision later on that runs better. New stuff: Stuff that you don't care about: The town. Still in a fairly green state but at least usable. Yes some buildings are clearly unfinished, sorry about that. Time system. Time doesn't flow constantly because that's too heavy on performance but at different points thorough the day the lighting/sun position/etc is updated. Time events. Events that happen at certain time. Updated save system. a lot more parameters are saved now and the bugs of demo 1 should be gone. Still not finished though. A lot of updates to the dialogue system as well as new form of dialogue that's more suited for conversations with multiple girls at the same time. Grass(DX11 only). You can enable/disable it with f5 if you are getting low framerate. More stuff I probably forgot Stuff that you may care about: You now have a smartphone. You can use it to see the time or, if holding left click, to accelerate the time. Upgraded physicson hair, etc. Most notably you can grab "stuff" in the lewd scene. Ara has a new hairstyle You can see Ophelia naked. Like naked for real. Ara's and Faranne's houses (Faranne's fairly unfinished though). Ugly stuff: Unfinished animations and rushed dialogue. Sorry about that! There may be grass growing on rocks, etc. I have to basically place it by hand so yeah... Tips: If you feel like you can't do anything else (protip: there's always something to do, if not there's an automatic timeskip) you can accelerate time with your smartphone for new events to pop up. There's tons of branching. You will not see everything in 1 playthrough. You will miss a scene regardless of what you do. There is 1 lewd scene and 1 non lewd scene. Red choices are a thing The crab is not a lie You may find cool but irrelevant stuff if you try really hard. Known bugs: The signs that pops up when you enter a new area is not working. This build doesn't contain the Lake, Forest or Adeline's house areas so that causes the sign system to break. DON'T CLICK THE BENCHES.I made those a long time ago back when the town was completely different from how it's now. At some point the system that allowed you to sit on them broke. If you click them you will be unable to move so you will be forced to quit the game. If you Save and Load after Ophelia "changes her clothes" she will be back to her original appearance. This is because I haven't officially implemented a clothing system yet so there's no way to save the changes. There was a bug that would cause an early scene to pop up in place of the lewd scene. I think it's fixed but there's a possibility it's not. The scene change relies on the save system and I don't trust my save system a 100% at the moment so beware. There's no icons when scrolling for items. You will have to try 1 by 1.Sorry about that, I'm in process of updating the inventory system. After you lose an item, if it was you active item your hand will be empty after right clicking. Just scroll the mouse wheel to change to change item. Eyes going crazy when fast movement happens. Need to tune the algorithm. TL;DR left click when using phone to accelerate time f5 to disable/enable grass if you want more fps. don't sit on benches 2018/12/07 Added Fuyuko build

The game has potential. There are decent animations, content, and even a plot. But the gameplay is frustrating. The character moves quite slowly, and the wolf, which can be ridden faster, is called through a bunch of actions that need to be repeated when moving to each location. And why is every transition in the game accompanied by a bright white flash? Even when you enter into a dialogue with a character, your eyes burn out as if you are about to be declared the next divine apostle. For some reason, you can't jump in the game. This makes you have to find workarounds for centimeter-long obstacles. Sorry, but there are basic requirements for first-person perspective games that need to be met to make them at least not annoying to play.

Im reviewing this game after years, so my memory may be a bit fuzzy but. this is a really good game even if unfinished. The best 3d monster girls you could ask for. Some of them kind of scared me and its all really freaky however, if you can handle that then this this is the game for you. I mean some of these girls are MONSTER girls, the ones you might not want to be near with a 10ft pool.
TremblingEmbrace 2025-04-09
Easily the best 3d porn game I've played. It has plenty of content with a bunch of unique characters. The game has a great mix of sexual acts that you have with each of the characters, making each girl really fun and the sex scenes very entertaining.

Let the dev cooks for a few years and upon coming back, it was abandoned. And his reason sound similar to YanDev "situation". Some people making a few game to earn reputation while some get abundant followers from their demos and then abandon the game. Money corrupt people. I really like the game, its idea, its story. Although there are some noticeable anime clichés , they are goofy and fun. Still list it as one of the top favorite games in main Steam account. Shark girl best girl.

i remember seen this game on steam and downloading it i thinked that it was an abandoned project but it seems that got some content before being abandoned the animation are fine but kind of goofy sometimes nice desing but i think they are a waste, the story is fine and jus that. i feel it like an yandere simulator kinda problem, it has some fps problem and bugged animations 5/10 mid game

First impressions of the game.. weren't great. I don't think I ever registered that it was an abandoned project and was abandoned many years ago, so I was surprised at the artstyle used as it seemed very outdated, but it slowly grew on me. Animations are a solid 7/10 - viewing angles often obscured view of the action but other than that they were pretty decent. Some questionable ones (which is due to the nature of some of the characters) Story was ok at first, got slowly better. 7 or 8/10 - It was engaging enough for me to be disappointed when I reached the end. Characters are very diverse and cover most kinks, shame that a lot of them didn't end up being developed much. 8/10 Overall, I enjoyed it!

An excellent 3D hentai game with lots of monster boobas and ass cheeks. You play on an explorable island and figure out piece by piece on how you got here. This game looked good and the scenes were enjoyable. I still remember it to this day, so 5/5 if we're talking about an initial demo review. Now, fast forward over 5 years, when I originally found this game, imagine my shock to see nothing was developed. We never got to see the backstory of that one robot chick and why she disappeared, we don't see how the incoming human invasion was handled. As far as I remember, redamz was working on the story at his own pace, as well as the fact Patreon shut his channel down because of some of his writing. How much of that you choose to believe is up to you. Overall, the game was never finished but from the brief demo I played on Steam a while back I enjoyed it.

The game is great and should be tried by all that is willing. The 3D models are very well rendered and animated. This game was a gem amongst the Adult Video Game community back in 2018, 2019 There's multiple scenes with it's various base girls and the addon content is nice and unique in their own right. Unfortunately, this game has been abandoned for 3+ years by its lone developer, their patreon page has been taken down, and all subsequent accounts gone dark. Rest In Peace, Monster Girl Island. You were too good to be true, and let the last of your name fade from existence.

Models are nice, graphics and design is mediocre, music is mediocre. But the killer flaw is something entirely different. If you are playing games for escapism, stay away from this one. I'd like to think I'm an open minded person and whenever i'm repulsed by something i think is outlandish, i give it a try, so at the very least I'll understand it better so i don't feel like a prejudgemental arsetard. But for the life of me i don't understand people that get off to being humiliated. Nearly every single one of the characters give you sh*t for no reason. If it's gonna be like that, give me the option to be an asshole back. You have no choice but to ask "give me more lol". How can anybody enjoy this? This is madness. Never been glad to see an abandoned tag on a game. What a waste.

This game is HOT. I absolutely love it! I'm not really into furries or monsters but this game made them really sensual. I gave it 4 stars because it is a bit short and the sex scenes could have had more options and sounds. Besides that, it is truly fun and exciting. I've heard the creator of the game sort of gave up on the game which is heartbroken for me. Many porn game masterpieces are abandoned these days... I hope he finds the will to continue this amazing game!
Paarl 2021-09-01
Well, after playing it I must admit that I liked it a lot, because of the images I honestly did not have much hope but hey, not bad, maybe it has some minor bugs but outside of that, the animation, story, H scenes are very good, maybe they should give you The option to advance the chapter when you want, not when sleeping but hey, that's my only complaint. I hope you continue like this and you can bring us more monster girls
Rethos 2021-06-21
This game is a pure scam. Basically no development since over 5 years. Also the dev is toxic af. (just take a look at the 8ch thread about this "game") I don't know why there are still so many people supporting that scammer.
Boldano 2021-03-10
There is a lot to consider for both the pros and cons of this game. As for the pros, what is in the game so far is very high quality. The game looks great and runs well even on my old laptop. There is a diversity of monstergirls to see and some of them have pretty good H-scenes. If you like the shark girl or frog girl, you'll probably be happy with what they have so far for content. The free roam feels pretty good and its fun to go talk to the girls you're interested in to see if they have any content. There's a lot of people complaining about the story, but it is interesting enough. As for the cons, even after all these years, there's just not that much of the kind of content that people are looking for. Most of the girls have 1 or 2 H-scenes, while some have no scenes at all. It looks like the plan is for each girl to have 5 levels of affection to fill out, so it is plain to see that there is a massive amount of content missing after years of development. Even with the girls that have H-scenes, some are relatively soft or niche scenes, so whether you'll like them or not is uncertain. Development progress seems spotty so there is no guessing how much longer it would take to complete the game or if they will complete it at all. In the end, it is worth a shot. What is actually in the game is good enough to keep you entertained and worth a try. However, I wouldn't get too invested in the game or follow it closely. Download whatever build is out right now, have fun with it, and then check back on progress every few months or so. Buying into the hype right now seems risky with how long its been in development.

(I originally wrote this as a post but got carried away and accidentally ended up writing a review lmao) This dev has talent but is a fraud. I first came across this game years ago and enjoyed the demo. But looking at it now I'm shocked at how little progress has been made. Patreon creates a huge incentive problem because patrons get charged regardless of how much (or in this case, little) the creator does, so creators are incentivized to milk their subs instead of doing actual work. MGI is possibly the worst example of this. This dev has made literal millions , a life-changing amount of money, for not doing much. Some creators have morals and will pause their Patreons if their output is low, but not this scumbag. The sudden wealth must have distorted his view of reality and turned him into a narcissist/lazy entitled snowflake. But equally at fault are his subs/simps who enable this exploitative behavior by continuing to pledge. On one hand, people have the right to do as they please with their money, including throwing it away. But at the same time, I think Patreon should consider reviewing creator pages or creating new rules to make sure consumers are not getting exploited. Either way, as much as I hate to admit it, this guy is kind of a genius. He also came in at exactly the right time, just as the Patreon model was taking off, along with MGI being one of the first "indie" 3D adult games that didn't look like dog shit.
Strox 2020-11-23
phenomenal, if you are looking for something good i really recommend this, i'll not post spoiler, worth spend time. waiting for more uptades, scenes with very good sound and 3D environment, which make it look really like you there
LivaNielth 2020-11-14
Although it is told in the rules that review should be about the game and not about the developer, this game suffers hardly from its developer that it would be misleading to not to also talk about him. The game, when it first came out, was revolutionary. It delivered what many people were searching for that time: 3D visuals, good graphics, good story, cute girls and quality sex scenes and VR support. Still to this day the graphics, nice 3D visuals, VR support and cute girls still stay the same yet the development of the game has now came to an undesirable state. The developer tries to milk the game's supporters to such an extent the charm of the game is now gone, with nearly-yearly updates and not delivering on what the audience actually wants, the sex scenes. I am not saying developing the story of the game is a bad thing, but most people play the game for its lewd content and story shouldn't be its main focus, rather what holds those sexy times together. This also hurt many fans with the 2nd 4th day update, which only brought insane lore dump and confusing development without any sex scenes. Still disregarding the developer's poor practices, the game still has its unique soul; with cute girls, quality sex scenes and somewhat interesting story. If you want to experience this game, play it once or twice thoroughly and then be done with it. If you try to follow its development and wait for the next update, you will be quite frustrated.

I really enjoyed this game so far and have reached chapter 3 (Im guessing im not far at all) but im gonna review the startup since that's generally what makes or breaks a game for many. Animations - Excellent 9/10 Not images but scenes. Sometimes interactive ones. Smooth animations, though sometimes clunky controls. The fixed head positions sometimes feels suffocating. Story - Not even gonna bother, havent even really gotten into the story itself. Movement - 6/10. Movement is clunky at times, though I understand it to some degree. Slow though which makes some sections, especially just movement sections seem long and boring. Glitches - Ive not encountered any. No performance hiccups either I've looked at the grass but turned it off. Ambiance - Lackluster tbh, the music is nice but generally, lack of texture sounds and things to catch the eye combined with long walking distances makes boring moments. Cookies & exploration - I've met a couple of cookies in the game, the pigs are cute. Exploration is nice though given these games clunky movements I'd like some method to know where an area is devoid of anything interesting. Also just a warning, if you dislike bestiality & furry then i'd avoid the fish lady right at the start. Too inhuman for my tastes. The others dont have that issue so far. My general advice for the DEV. Make the main character movement speed faster. Though I do understand if you dont as it can cause bugs and more issues than its worth. In that case, or even not if you haven't already, add some tool to teleport, even if it's a command-type tool it would really help keep interested in the game. The lack of ambiance is probably my own fault in some ways by disabling the grass etc.

will write a review later but so far best monster girl lewds around and rich in story. only downside is the waiting time for updates but understandable though because the creator is doing it alone and it looks like he stays alone to create his vision which is respectable. my review will never come like the game itself wont be updated, f.
Deleted member 1096745 2020-09-02
ah...right here we go again another good 3D monster girl game positive (my opinion) : -nice lewd animation with good wet sex sound -smooth expression and body move -my favorite is slime girl negative (my opinion) : -need fix player movement because it's so slow for me -need fast text talk advice = add pregnant genre >w< okay just that from me
spongecake 2020-08-30
I've been following this game and have played several versions of it. This game is interesting to me because of the monster girls and that it's the first 3D game I've heard of about them. Certain things from the game are quite buggy such as the UI and movement, especially riding on the wolf, that thing is a nightmare. Some animations pop in and out (not too big of a deal) and sometimes I find myself bugged into a black screen because I'm trying to skip the dialogue I've already read too fast. Storywise it feels really long and cluttery, sometimes I would completely forget what it was all about because some characters just won't stop talking. This last update felt really disappointing, but since it isn't finished yet some aspects might be improved (like new scenes and such) but I have low expectations that the story will change. (the story parts of this update felt really stupid imo, like cmon man I know you need some drama but still) H-Scenes are 10/10 in my book tho. At first I tried to be somewhat invested in the story but I found myself lost after not too long. If you want to play this game purely for the H-Scenes go for it. But if you are in for the story, give it a while until it gets to a point where it doesn't feel like walking on legos everytime you try to understand it.
