You can move the green ball with the arrow keys, WSAD, mouse or touch. Hit SPACE to choose the menu options, or to exit the game. You have to collide with other balls to blow them up.
If they had higher charge levels than you, your charge will drop, if they had lower or equal, your charge will increase after the collision. If all your charges are depleted, the game is lost. The goal is to destroy all the other balls.
In the settings menu there are three difficulty choices:
- kid mode is no death/no score,
- normal would be a randomly generated puzzle what you have to solve for a given score (more difficult puzzles award more points!), and
- maximum score mode is for the real wicked. You cannot make mistakes here, not even one.
