About
Your hopper bounces on its own; you only steer. Platforms are spawned within jumping range, then mix in sliding, crumbling, one-use cloud and spring platforms as you climb. The sky darkens into a starfield the higher you go, screen edges wrap around, and stars on platforms give bonus points.
Objective: Climb as high as possible without falling off the bottom of the screen.
