The game looks promising.

The girl designs are actually nice. Definitely above average.
The visual style works too.
The colour palet and camera angles are OK. A bit above average Id say.
The story is definitely above average and the setting works.
There 3 main down sides.
-
the H animations (especially the first 3) and overall "cheapness" to the H scenes.
The girls look really good so once the H scene starts, the player wants to enjoy it, but with one simple animation it feels insufficient. Even tho some of the koikatsu animation are well know, they just work. I would say it more about the design of the girl then about the novelty of animations.
-
the grind has no progression.
Maybe its planned in future. But right now it makes little since. After capturing the casino, it should generate some money so that the grind makes more since. No need to mini games.
-
No sense of progression with the story nor the girls
Right now the UI is made so that I don't know which girls there are. What events are in the main story and what events are only for each girl. So I don't know what to work for and what to expect.
Good luck with the game!
