In this game, you'll have to face down numbered orbs that float all around. You'll have to shoot them as many times as the number on the orb says and in some cases, the orb will split, triple or quantize itself into multiple orbs and making it even harder to take out the enemies of the empire.
Collect the raw materials you'll need to repair your ship if you get hit. If you are prepared it'll only take a few clicks to repair yourself if you are not prepared it'll for sure spell your doom.
