I loved the music and art! You may want to use a bit more lowpass filtering though since some of the higher frequencies sounded a bit loud for me. It may also be a good idea to make it more obvious when an input is going to hit or miss (I had a lot of inputs that felt on time but didn't move the character). Other than that, this was really fun, and such a great idea for a rhythm game! Awesome execution, especially with how everything moved with the beat!
