A really cool entry! I thought the idea of not just pressing buttons, but being a button to be pressed, was an awesome idea! The puzzles were well designed, and I think the graphics looked great (very fitting in a 3D puzzle game).
I have only 2 main critiques. First, the camera seemed to shake a lot, especially when I was just beginning to move in a new direction. This made movement somewhat disorienting on my end. And second, I think having some sort of game over screen after the player falls would be nice, so players don't have to manually restart the level after falling.
But still, I think this was a great game with a neat set of puzzles. Well done!
