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!
