Art style is adorable, music is some of the creepiest I've heard.
I'm not a big horror person so you better believe that I wasn't brave enough to complete the game but that's okay. I obviously wasn't the targeted audiance. 100% recommend to everyone who's any% braver than I am.
Update: watched a play through. Honestly the game wasn't as scary as my mind was telling me. The music gets less creepy after the door and the tone becomes a lot more wholesome. I 100% recommend this to everyone. It's not really a horror horror game, just a game with a darker tone.
