Always nice to see 2d/3d hybrid entries, it's a style that I personally love. The concept is great and I love the between-level stuff (the screen showing the floor and the loading screen), it has a lot of style. Music is quire fitting for the scenery.
It was a bit hard to understand at first, but it can indeed be figured out. Some items I had trouble picking up since the interaction area seemed quite small, but that's not too big of a problem.
Pretty good submission over all, cheers!
