Just like Gyruss! Only not. I was expecting the reverse joystick control (this is just like Gyruss, right? I read that somewhere) past 90º. So, in order to travel a full circle, you move the joystick in a circle? For some reason (spaceship truckers?) my thrusters are all fore and aft, since forward and backward movement are insanely fast in comparison.

I would have liked some colour, everything tends to blend with each other.

I got bored after the third level.
