I really like this design! i don't think I've seen a circular take on Breakout before, and the added mechanics like flipping sides, parrying, sprinting are cool. If you happen to build on this idea after the jam, it might be interesting to provide an additional bonus to parrying (maybe a perfect parry can destroy fireballs occasionally). I might also suggest adding a disadvantage to sprinting, or having a stamina bar so you can't sprint forever. Very nice work on this one, overall! Great choice of music, and the pixel art and color palette is really effective!
