Nice idea, although not original (see Vector Runner). Good graphics, sometimes the edges looked flat. Good music. You really need a menu to speed things up. Some suggestions would be to add multiple modes (timer with points, 10 lives, farthest distance attainable), you could also make the game harder by the farther you go the more the board rotates and eventually rotates to 90 degrees(this could also be another mode).Overall 3.9/5.

Collision detection seems kinda spotty, and the way the play is designed, it seems quite hard to avoid the enemies through skill for any period of time (especially if they pop in front of you.)
I like the control and music well enough, it seems the bonus circles are undervalued because of the bonus for distance (and therefore boost.)
