Disposabot

You are a simple, citizen-class robot who has been abducted by Dr. Nemesis and forced through his weapons-testing facility. The good news is that he has replicated you, so with each horrid death comes a renewed hope of escape. Pass all 21 of his "anti-hero" rooms in this puzzle-platformer, and he will allow you to escape. But can you acquire the five keys that give you access to Dr. Nemesis himself, so you can exact your revenge?
