Choose between four different characters, or fighters, in this side-scrolling shooter. Each has different abilities, as well as a different skill and pet. In the actual game, use the WASD keys to move, the J key to attack, and the K key to use your skill. If you would prefer to use different keys, you can choose which key responds to which control in the settings section. There is no penalty for letting your enemies fly by, so if there's too many to fight, try to dodge them instead. You will get more points for killing more enemies, however. Reach the end of the level to pass each episode.
