I was able to find the culprit YAY!
I really love the pixel art inside the building, it's gorgeous! The music is really fitting too!
I also love that you find contradicting clues, They're very clever and made the game fit the theme really well!
I also think the difficulty was reasonable.
My critiques:
I personally think there's no real point in finding the note that contains info already gathered by the player themselves. If I'm not mistaken, everything in the note was already told to the player. And since all detectives already have a note, why not just give it at the start?
I think the UI could use some polish. I don't think it really matched the vibe of the rooms.
The apartment pixel art felt slightly rushed too (Maybe due to time constraints)
And of course, the game need some SFX!
Other than that, really nice game! Great Work!
