Fits perfectly with the game jam theme. I saw a lot of games about forging in a similar manner, but none of these, as far as I know, cared about finding the materials. The exploration alongside the ghosts gives the game a unique twist. I played with controller, as I saw you recommending this in discord and it as a pleasing experience!
Something that I noticed that could be improved, is the tutorial. At first it didn't really understand how the controller and buttons worked. I guess that's complicated since you are supporting keyboard and controller.
Congratulations!
