Keep your finger on <a href="https://geometrydashwave.com/">geometry dash wave</a> or press the left mouse button to make the ball jump. When you release the button, it will fall back down. You can touch the floor or ceiling, but you have to avoid the obstacles that are coming your way. If you touch an obstacle, the level starts over. To finish the level, you have to survive until the music stops. The controls are really simple, but the game is really stressful.
