I did not expect a deduction game in this jam to be honest! Although I like the music and the visuals, I think they do not mesh really well together, I the music is a little much too light-hearted for the visual style, and seeing the endings of the game, I think the visuals are a little too serious for the vibe you were going for. (Unless the contrast was wanted, in that case, good job!)
For the gameplay, I think finding the notes and using the information works well enough (although some notes are pretty hard to find) but I wish there was an extra layer to the house exploration, either by having an enemy in the house or more goofy stuff (something like a haunted house)!
I really like the concept here! So I hope you'll push the idea or the visuals further!
