Use the arrow keys to control the ball, yellow is the level end. Certain colors are bonuses but watch out for blue, you can drown and lose time. If the game glitches out click on the stop sign then re-click on the green flag, do that also if it doesn't play the music or if you want it to play something else. you can move around the score and time variables if you want to by dragging them around.
Simple platformer?
