Playability:
Once you get off the podium in the beginning the game is incredibly straight forward and well done. I would suggest changing the interaction for the first puzzle as there is no indication on how to solve it at first. Some kind of interaction button would go miles here.
Theme:
Directly ties to the theme and feels good overall. Good work with the environments and having vision/sight tying into the puzzle mechanics.
Cleverness:
Really good mechanics on this and ones that feel non-standard. Would love to see this expanded in a larger game.
Artistic Style:
Consistent and interesting throughout. Making fully modeled environments and textures in a short timespan is difficult and you rose to and exceeded that challenge.
