The game works fine (that is, after changing time regional format), no challenge at all (except patience), you just fill her with food, fill her with your other food, get points, shop items, and that's it.
Scenes are okay, but alas, to get point you need to fill her with your "special coins" wich are limited by day.
Sexy time are as follow, first time you fill her, you get a scene (with text and voice line, chinese or japanese to your liking), then each time you do the same scene (Like H her when she get on her bed), you get one of those annoying filling bar that takes forever to fill (Like game of desire flash games), with no interaction whatsoever.. So even with not much content, it still feel like an endless grind of scene you already saw just one minute before.. At least you can just fill one bar and then use special coins as many as you have, you don't have to fill one bar for each coin.
You can choose to tell her to go interact with each object you place, only a bunch of interaction she only do when she feel like it (she sleep at her own pace, eat twice a day, etc.).
Food cost money and feel her food need, aside from that not much.

No mini games, it's just a glorified gallery, at least it looks and play ok i guess.
