The recycler is slightly useless as you can recycle items manually... Also, Junk items slightly unbalance the game as you can basically get materials whenever if you stockpile Junk.
Ways to improve this: add something like an opening title, add a score, make it look more interesting (not just black and white) fix the bounce (as it bounces about 1/4 of the way down) Maybe when it hits the floor you loose?
