Hello, once the game has started, only use the space bar to avoid objects ! One pressure, the ball goes up one floor, another, a second floor and third, it reaches the last floor.  After three seconds, whatever its position, it returns to the level of the first floor! Be careful !

When the ball meets a box of its color, it becomes invincible for 3 seconds ! At each checkout, it accelerates... And changes color ! One goal: to be the best! Have fun !
