Sense
Magnetoception (or magnetoreception) is the ability to detect the direction one is facing based on the Earth's magnetic field. Directional awareness is most commonly observed in birds, which rely on their magnetic sense to navigate during migration. It has also been observed in insects such as bees. Cattle make use of magnetoception to align themselves in a north-south direction. Magnetotactic bacteria build miniature magnets inside themselves and use them to determine their orientation relative to the Earth's magnetic field.
Magnetic Joe
When Joe passes near a magnetic cell his magnetism activates. The player can see a lightning effect between Joe and the magnet, and Joe moves towards the magnet. As he moves closer to the magnet, his movement and rotation changes. The player can control the ball's movement by timing when the magnetism is activated. Different magnets push or pull the ball in different directions and are marked accordingly.
