Your only weapon and primary puzzle-solving tool in the game is a solid mysterious metal sphere that you have to manipulate to overcome the challenges of the game. There are various ways to use Ball in the game. It can play the role of a platform to help you reach high places over traverse gaps. Many puzzles require guiding ball to a specific place. Besides puzzles solving, there are random combat sequences in which you also have to use the Ball to smash your enemies. During the game you can upgrade it by changing its properties like covering it with spikes, overcharging with electricity or changing its gravity field allowing you to jump higher when you are near the Ball.
