A puzzle game is always cool. However, I was a bit weirded out when the rooms were amazing , the enemies look cool, and then the user model was just a basic unity capsule. Just plastering a t posing model would've been so nice as an addition.
More instructions and some way of keeping track where you are in the game would also be extremely beneficial. It's kinda hard to keep track where you're going and then all of a sudden you die and your back at the beginning.
