Power Ball

Click on the place where the Power Ball is to be moved. Defensive discharges and charging of the port are performed by a single red button at the bottom right. You can access the unlocked port auxiliary functions with the three buttons on the left. If you're playing on a computer, you can press the space bar instead of clicking the red button. Auxiliary port functions then in the game release keys 1, 2, 3 (not on numpad). The yellow and blue lines show the state of energy and discharges.
