Great concept! Would be great if there was a little more control over the movement, something like a left/right while on the platform for example. 

Pretty cool idea for the theme; it reminds me of movies like Rollerball and Death Race 2000 (minus the murder anyway...).  Having finished all four stages, I got more of a feel for the spinning mechanic over time, but the actual visual of the player really does not reflect where he goes when you launch him from a bar.  With all the bouncing, the first level actually feels harder than the others.  I also found a softlock in the second level, but style points for "Sick Beats" at least.

I think there is a lot of potential for fun movement with more robust physics-based movement (at the same time, the way the player course-corrects autonomously is pretty neat).  The backgrounds are pretty cool, too!

I found it quite tricky to judge which way my guy was going to be launched when swinging, maybe adding some kind of indicator would be good.

I don't understand how the swinging mechanic works.
