PRAISE: I like the the inclusion of the custom textures and video, as well as the basic animations. Throwing the boxes can be fun. The atmosphere in the ending corridor was the most impressive aspect of the whole experience for me. The very end made me laugh, though that might not have your intention.

CRITIQUE: Interacting with the boxes is pretty janky. I would've liked a bit more variance between levels, and the level itself could be designed to look more like you're going from one nearly identical room to another, which I believe was the intended effect. Right now it feels too much like you're still in the same room, rather than entering a new but similar room. Fixing this might be as simple as rotating the player to face into the room after the fade to black, as well as adding a door to the other side of the room for the second and third levels.
