It looks great and the mood is very spooky, made me feel like I was going through a haunted house at a fair. The music volume was a bit loud at times, couldn't hear what the NPC was saying sometimes. The music made it more oppressive than frightening. Then all sound suddenly stops after a couple of minutes. Almost made it more frightening then.
Had to restart twice in the music room, the piano interacted only with the player collider, not with the hand. Made it difficult to press less than 5 keys at a time. Couldn't find the solution. Possible that I just didn't get it though.
Same with the reading room, placed the books on the shelves, tried rearranging them but didn't get any feedback if I've done anything either wrong or correct. Still, might have just missed something...
Convai gave out error warnings every other sentence.
Good effort though! Very spooky! Would love to play it later if the bugs get ironed out!
