Extremely difficult, like a more 'arcadey' QWOP or Getting Over It type beat. Hats off for offering some nice accessibility options. You may have noticed, but the sound defaults to basically being off, almost leading me to believe the game had no sound! Which I'm glad I caught cause your music was very cool and varied.
All and all, a really fun, whacky concept. With a bit more polish, this would be a really fun time-killer arcade game.
