What a cool concept, and quite fun too! Though I think sound effects could have gone a long way to make the game seem even more "hectic" and even more "too much-y", like pipe thwoomp sounds for each item that gets shot out of the ducts, meat slapping sounds when things hit the floor, etc.
A sound effect to indicate that the player has picked up a correct item would have been nice too, since I sometimes didn't notice that I somehow picked up the correct item, and didn't notice the change in the GUI on the side.
Anyways, this was a very cool game, and I enjoyed it!
