The movement is very good but I have some issues with the execution. The lack of a simple letter grade is an odd omission since the point goal of each level is very high and I never found myself quite reaching it. It would have been nice to receive some reward for my effort even if I didn't get what would qualify as an "S".

The game also feels somewhat at odds with itself. It's at its best when you can keep your combo going for a while but the levels don't seem designed to allow you to do that very well with platforms you have to wait for and the like. I assume you could speed past all of this if you were skilled enough but for me it was kind of annoying. Still, a pretty fun and charming experience.
