Excellent entry! Loved the visuals and the puzzles and flow of the game was well put together. The light guy certainly scared me. Very cool way of messing with the player.
I will say that the controls were a little unorthodox. Throwing props with middle mouse click and left shift for crouch were odd choices. And it would have been nice to have mouse control over the inventory. I also feel like some music or stronger ambiance to the sound would have been great for the atmosphere. And there could have been more feedback from the audio.
Having said all that this is easily my favorite submission so far. Well done!
