Twinkle Star Sprites

The game plays mostly as a vertically-scrolling shooter, with you controlling your avatar and attempting to shoot and avoid the incoming enemies. The difference in this game is that each player has his own play area, a la Puyo Puyo, and the enemies cause splash damage around themselves when shot. Thus chaining the destruction of several enemies creates a combo that performs an attack move on your opponent. These moves can range from targeted fireballs, to special moves unique to each character, to the summoning of special "boss" characters that the other player must destroy before continuing.
