Galactic Crusader

As an inexplicable butterfly spaceship, the player must kill anything that moves in this upbeat vertically scrolling shooter. Enemies cascade down the screen in a myriad of scattered formations, and the player is tasked with wiping them out. Downed UFOs occasionally drop capsules that contain different shot types, such as lasers, spirals, and waves; these can be stacked if another pellet of the same color is picked up.
