Basically, the concept of the game is a mix between a coordination game that requires you to move two different ships at the same time using a different set of keys. (w,a,s,d;i,j,k,l) and a fast shooter game with multiple enemies.
The game features two different game modes with up to 21 levels of play. You will be moving two different ships around, and people seem to love shooting stuff, especially when it includes retro explosions! Have fun playing the game!
