I am honestly kinda torn with this one. On one hand, the models are pretty good, the events are well done, and when it works it's a pretty good game. unfortunately, it rarely works. The game is designed in such a way that if you don't follow the Walkthrough exactly, you end up throwing yourself against every wall until something new happens. Instead of fixing the game to function better, the dev instead tries to give us a walkthrough and a gallery guide to help us figure it out. however, the walkthrough becomes gradually nonsensical as events are placed in the wrong place, and even if you meet the criteria that the gallery tells you, some events simply won't trigger. Then there is the FLY. Oh lord, the FLY. The game introduces a concept where for some unexplained reason, the MC have a pet fly that can remote images to him. throughout the game you HAVE to use this thing to unlock events so that you can progress to the next episode. HOWEVER, the FLY has a level that increases as you use it and certain events won't trigger if it isn't high enough. What's worse is that you have to wait until the very last moment of an auto scroll segment or else you won't get credit but if it goes past that point the FLY dies, you don't get credit and you can't use it for the rest of the day.
Any comments in this Thread asking for solutions to these problems are met unanimously with a link to the dev's discord, saying that we would find our solution there. The "solution" is the same broken ass walkthrough that didn't work the first time and a series of 100% saves. Because apparently the game is so broken that the dev stopped trying to fix it and just opted to give us cheats to get to the next part instead of letting us play the game.
In short, don't bother. The game is broken to the point even the dev has given up on fixing it and you can find equal or better 3d porn elsewhere.
