Use your mouse to draw a path that the ball will travel on to a flag. This is the only way to complete the level. You should try to draw the line in a way that will also let you collect all of the stars in each level. This will not be easy because the path you draw crumbles underneath the ball. The line needs to be as fluid and smooth as possible and it needs to curve in a way that will force the ball to accelerate as quickly as possible. If your looking for a challenge you should definitely play this game.
