Your goal is to reach the bottom left corner of the maze. If you reach the goal-platform, youll get to the next level.
With each new level the maze grows, until you reach the big-boss-level 11.
To move the ball tilt your device in the direction you want the ball to roll. The harder you tilt the faster the ball rolls.
Also you can make the ball jump by tapping the screen. But you have only a few jumps per level, so use them wisely.
