Interesting that you don't actually die when you get hit.
I'm a complete geek, so I would have liked to see calculated 'collisions' happening. Like when two objects collide, their resulting velocities are calculated by Newtonian equations.

scroll down to the "Two-dimensional collision with two moving objects" section
Interesting game however I fell like the outcome of the game is determined more by the randomness of the objects you're trying to avoid than the skill of the player. The moment felt good and getting hit by an object, spinning out and regaining control is fun. The green lines do make the game harder but feel really out of place. A big, slow space ship would probably fit the game better.
Thanks for the feedback guys, Yeah, I don't know what I was doing, it was going to be a platformer first but than it turned into this :/
