I think this game has huge potential, but right now I'd give it 3/5 stars.
2 stars for the graphic style and the characters; they are honestly incredibly good.
1 more star because the game is actually entertaining, the dialogues are good, and the mechanics aren't boring or forced.
What it lacks:
I don't give it 5 stars for 2 things: the game is still extremely unpolished, and that AI scene.
As I've said, the game has huge potential, but it is still full of bugs and unpolished. For the moment most characters lack scenes, and some of the scenes are hard to get; maybe it's a skill issue of mine, but I find lust hard to increase sometimes. And some requisits are hard. (The guide in the phone is appreciated, though; without it I wouldn't have found most scenes.)
Also, there is one scene that is made with AI, and it's honestly terrible. I do hope it's a placeholder.
I've bought the game, but for the moment it has little content, so I wouldn't expect much, but if you believe in the project (I do), it's cool if you can support it.
I'll hibernate for like 6 months or so; I hope there are scenes of "rich waifu" and "lazy waifu" once I come back. Best of luck in the development of the project; you've got gold in your hands, Quiquersson.
