The dynamic of game is easy and the controls are very simple: use the mouse to rotate the ship, scrollwheel to adjust speed and left button to fire. You can use the right button to zoom.
Probably, what is amazing in the game is the scenery, which is mathematically generated. You'll fly throughout fractal designs.
It's an original game where you have to fly around, shoot enemies while dodging their bullets, all taking place in a trippy scenery. Oh, to repair the ship, just fly close to stars.
It offers 5 different difficulty levels, and the last of them, called insane, is really difficult.
Finally, it also includes an scenery creator, so you can play in your own mathematically generated environments.
