The game's scoring system is based on enemy color. All enemies are one of three colors: red, blue, or yellow. Destroying three enemies of the same color in a row nets the player a scoring bonus. Killing another set of the same color increases the bonus while shooting another color will reset it. In addition to gaining a higher score, chaining attacks on the same color increases the effectiveness of the weapon used to destroy them. The weapons stay powered up for the remainder of the game. The player can also obtain extra points by destroying bosses more methodically. Each boss has different segments and appendages that can be destroyed before targeting their weak spot. If all these segments are destroyed first, the player will earn a greater bonus. There are also hidden dogs that when shot, will give the player bonus points and unlock more game options.
