The ability to switch gravity on both axes is super unique and fun to play with, and it's such a cool feeling when you do cool maneuvers with it, like in the spiral level. My only complaints about the level design are that some levels are too strict in their timing requirements, and I felt like I didn't have as great of an understanding of the switching as I needed earlier on. But in most cases, once you gain an understanding of the gravity switching, the obstacles are extremely fun to learn and blast through. And I really liked the nice touch that the music was more laid back after you died versus when you were playing. Great job!
