Shoot your own shots with other shots without shooting yourself.
Charge shots before you shoot. Bigger shots are worth more points and move faster. Shots can only be destroyed by a shot the same size or smaller. Hit a big shot with another big shot to clear the screen.

Left/right - rotate
Up - accelerate
Z - hold to charge, release to shoot
