Cool concept! Centipede meets RPG! A few ideas, I'd throw instructions into the game itself, rather than just in author comments. Also, you can hold down primary, or secondary, and still move and shoot, but if you hold both down, you cannot move at the same time. I'd also recommend, since you can use WASD/Arrows, you add an alternate set of fire keys, besides J/K/L, like Z/X/C for people using arrow keys. This game has potential!
