Prior to starting, players have access to the configuration menu at the title screen of the game, where various settings can be adjusted.

Players can also equip the ship with a set of two satellite "options", whose positions can be arranged and attack at the player's will. At the end of each stage, a boss must be fought in order to progress further through the game, with each stage increasing in difficulty. If the ship is hit by enemy fire, the players lose a live as well as both the options and the weapon in use, instead of losing all collected weapons and once all lives are lost, the game is over.
