Hey there!
Just wanted to put some feedback here, for a week, the resources of having 3D models and remixed music in is really impressive, it's a lot to demand for 1 week, so it's nice to see it in there! The idea of having 3 different 'worlds' or layers of the world to explore for clues and items is a nice concept for the jam too.
In terms of some improvement (with the proviso that it was a short jam!), a bit of sound to give player feedback for interacting with items would help give the world a bit more life, just so that we know as a player when we've picked something up, opened a door etc.

It's an interesting idea (and the music and concept is cool too), so well done for submitting! :D
