Nice theme implementation! 

Navigating the maze is pretty cool! I tried using the light of other objects to get my bearings. Looks nice as well!

I liked the idea, the mechanics, and the models,  it just needs to be polished. Good job! :)

Puzzles were cool.  Not really sure why I kept dying though.  I didn't see any timer or anything and I wasn't running into the monster.   Would have been nice to have some more sound and possibly an indicator on which player is active or at least a visual queue when you switch players.  Overall cool game.  Nice job!

The graphics look cool, there is not enough music in the background at least some. I walked for a couple of minutes and suddenly died, I did not understand why. There was not enough health indicator or sound signaling the approach of the enemy. But the loss screen is also cool.
