I finished the whole game and the guide helps me finished 100% of the side quest. I firstly did the best ending and the normal ending (speedrun). I think i'm in love with this game because the other parts especially the best ending has cute and wholesome parts.
When i was playing yesterday, my mom looked at me playing this game and she said "that's cute", not knowing it's a horror game. My favorite part is the museum part when there's some stuff in there. But overall, i enjoy the game (I'm not really fan of horror games since most of them are very creepy, unlike this it's less creepy especially "The Grim").
So that's all I'm gonna say, have a great day!
