Recollection room is the last point of the game. Dev usually adds the save allow to start new update, so you don't need a lot of time to finish game.
P.S. It's all about part 1 now.
No need. I've tested it and I'm pretty sure there's nothing wrong with this part, either you're missing something or you've downloaded a compressed version.
Here is what I captured i think it might have to do with the mom side quest idk anymore.
Edit - I ran the game in Locale Emulator and it finally let me in the sweet shop but if i try to do any side quest before going to the sweet store it bugs out so I'm probably just gonna have skip the side quest
