These bells act as one-time power-ups, allowing the player to destroy every enemy on screen, fire huge beams of energy, etc.
The game also features extremely advanced graphics for the time period and system; most notable are the fully scalable 3D polygons present in one of the stages.
The Saturn version includes an "Extra" mode that rearranges enemy formations in the main game.
The PlayStation version instead features "Accident" levels, small segments that randomly take place once a stage ends and the ability to turn off the announcer during gameplay.
