Three characters for a scrolling shooter style game.
Their designs are simply based on circle, triangle, and square. Even their personalities are based on those shapes. Blue is pretty bubbley and happy, and not particularly sharp. Red is very forceful and pierces everything with both her words and her attacks. And Pink is pretty nice, but is straight edge and a perfectionist.
The three characters are to be controlled simultaneously by the player. Depending on which one is "active", the other two will fly in different formations behind her. Not much else is decided yet.
