🎯 The experience
Playing Gussun Oyoyo feels like controlling a hyperactive marble. The ball bounces constantly, making every move a test of timing. The worlds are bright and cartoonish, with a playful, slightly chaotic energy. You're not just solving puzzles—you're wrestling with physics.
⚙️ How it plays
You guide a ball through each stage by pushing blocks and collecting items. The ball moves in a straight line until it hits something, then bounces. You must plan paths and time jumps to reach the exit. It's simple in concept, but the bouncy physics make every level a puzzle of momentum.
