The Bouncing Ball is a homebrew Gameboy game made by HuCABBAGE for the 4th annual GBJam (2015).
In this neat little platformer with no music, thus only sound effects, you are in control of a little ball, which is constantly bouncing around. Your goal is to bounce through all the 50 unique levels by collecting every heart you can find on your way.
