There's not much missing from this game to make it really great! First of all, the pixel art is top-notch! The idea of the wheel spinning on its side works really well, forcing us to concentrate on all sides. You have to pay attention to your movements, boss attacks, the spinning wheel and the opportunities it offers. All in all, very good stuff. But I found it too difficult. Even in easy mode! I gave up on the second boss, because I couldn't anticipate his dash and ended up dying over and over again. If the bosses were a little less frantic, gave us more warning of their attacks, and gave us more time to act, then the game could really be addictive.
In short, crazy potential!
