The energy system is in danger. Control the Power Ball, collect energy points and charge the port in the middle. Enemy energies want to stop you. The Power Ball can be protected by several energy discharges. Each time you charge the port, you gain points that will improve the port, unlock it and improve other protection functions. The yellow line below shows the charge status of the Power Ball. Blue line supply of defensive discharges.

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.
