Really great job on the aesthetic! The game is stunning, and the animation synced to the beat work realy well.
I also like the game-design and the simplicity of the concept. Although I had a bit of difficulty to really get into it. Maybe because the game ran at 30fps, or because there was a slight delay, I never had really the satisfaction of doing action on the beat. Even though I had a "perfect", it felt that it was missing something, like a sound effect or a flash. Idk, when I see the game in video everything seems there for it to work, but once in hand, it's different. (again, maybe it's because of the 30fps, I know that it can change the feeling a lot)
Also the level-design was a bit confusing when I started to walk on wall. I wasn't sure what was the optimal path, it was a bit too open, and I had diffiulty jumping from one wall to another. In the end I felt, couldn't get back up, and what was supposed to be a "final challenge" ended up a walk straight forward. :p
With all that being said, I still think this has the potential to be a really cool game! Its mechanics are simple but provide good challenge, its visuals and music make it feel like an intense running, and it's still satisfying to see everything synced to the beat (which is imho one of the hardest thing to pull up). I'm curious to see how it will progress! :)
