There's just too many things that went wrong with this game. Besides not making sense narratively (it's an h-game, so who cares), it also doesn't make sense gameplay-wise. It's extremely repetitive and way too grindy for what you get. The gameplay is not fun, nor satisfying. In fact, it punishes you for playing the game. For instance, the further you progress, the MORE repetition you get. Here's another one example: you can easily tell how much money you roughly make per day, so you know in advance that you won't be able to make it past day X, yet you're forced to play though that day anyway (which can later on take up to 5 to 10 minutes) with 0 rewards for doing so. It effectively just wants to waste your time. The gallery mode actually has a better pacing than the normal game mode.
And honestly, this just scratches the surface. IF you still want to play the game, just download a 100% savefile and only play the gallery mode. The animations are decent, at least.
