This is so nice and well done. The music switch when you go into top-down view is really good. Really impressive work!
My one criticism is that the character controller rotating away from things it collides with made navigating a lot more difficult than it needed to be. I couldn't figure out why my guy seemed to randomly turn, and at first i thought the green things were shifting around me. It added to the weird existential dread i was feeling, but probably not in the intended way.
