Nice work.
I loved the art style and the music set an excellent mood. I liked the idea of the game, solving mysteries, talking to ghosts, crafting items. I found it strange that I could still move around while talking to people, and the controls were unintuitive the whole way through. DA to move and IJ for interactions, and then arrow keys for selecting. I was moving my hands around a little too much.
Otherwise, cute game and I loved your take on the theme and object. It was very original.
Good luck with the jam!
