The game quickly gets boring as it consists of moving the mouse cursor in a circular motion over the screen to make the asteroids follow and smash ships.
6000 hp and 26350 base hp after day 3. I'm bored and quitting now. First get a full-automatic weapon, then get the HK, get all the enhancements and then go for the FN-Scar. Then get Jackhammer, and you can go on indefinitely. Truly. But boring...
