The player controls a cartoon-like spacecraft to shoot enemies. Bells appear across the field, giving the player power ups and bonus points with different color bells giving better rewards. However, it is possible for the bell to fall off the bottom edge of the field. By shooting the bell, it can be forced upwards and can be made to change to have a better rewarding color.
