Just came across this fun game, you need only to use one button.

Fun. But the boss is almost impossible. I stopped at 800-some clicks
Well that got old fast. Also don't see the point of having a C64 style loading bit if the game doesn't stick to a C64 aesthetic. Didn't like the way the basic sprites went with the smooth backgrounds. Collision detection on the jumpy platform bits was frustrating too.
