Players navigate a progressively increasing wave of obstacles in a procedurally generated environment. As the wave rises, obstacles fall vertically from the top of the screen, blocking the player's downward path.
To survive, the player must move left or right to avoid these falling objects, which vary in shape, size, and speed. The wave accelerates rapidly, requiring seamless movement and quick reflexes from the player to maintain progress.
Unlike other endless obstacle courses, the player's position is not static, and their goal is to reach the bottom of the screen, albeit the setup regularly changes shape, posing a unique challenge. The game runs in the browser without the need for download or registration, allowing for instant access.
