This is a really interesting concept! I like the mix of 2D for traversal and 3D for examining the mushrooms. I ran into two bugs though which cut my play through short.
First I had issues with the game crashing right after the main menu popped up after the disclaimer
Second after interacting with a mushroom my controls locked (I'm guessing the player got stuck in the dialogue state?)
I think it just needs a bit of polish! Definitely a unique concept and has lots of potential!
