Interesting, a fun simple platformer. The art style is really good, I like how each beat in a synthesizer software is also a platform. It feels like there's a great game mechanic you could have implemented. (Like the music is linked to the platform or something...)
I feel you man, having to spent a huge chunk of your time programming one crazy feature, only to find out you have no time left for the rest of the game.
Great work on the circular platformer, amazing programming feat!
