Interesting take on the rhythm game genre. I imagine count down is pretty much a core aspect to a rhythm game considering songs last a duration, so I can safely say that it fits the theme. It was a bit uncomfortable to the eyes though, especially when hitting the bars that switch the direction, or change the head, of the spinny thingy. But i think for a rhythm game it does work.
I am curious though, do the bars you have to hit match with the music in any way? Because I did try to use the music to maybe gauge when to click, but I don't think I got far with that... though maybe that might just be skill issue on my part.
