Interesting concept, the mixture of visuals was cool but I think the 3D sprites were way too big for the finding element. I think it could also have done a bit more on the collection or progression elements (like having shrooms unlock clothes or something to connect both aspects of the game).
The text in the menu was a bit hard to see, and most of the foraging seemed to be done entirely by accident (especially in the 3rd level). The shoes and socks never seemed to quite fit over the character sprite.
The eery atmosphere of the worlds with the sound effects was quite fascinating.
