Pretty good, and a good choice of focus with the whole leaf thing, but the game doesn't seem to really begin until about halfway through, and then the second part of the chase felt way too hard.
Personally I was kind of hoping that the whole game would just be about jumping in leaf piles, I feel like the dive jump you implemented was perfect for that, but the change in direction was alright too. I just wish the character felt a little less sluggish.
