Love the kickflip animation. The art style is very cohesive and sweet. I liked the music.
Unfortunately, while the skateboard is, indeed, gnarly, it makes for a pretty frustrating platforming experience. It's tough trying to floatily land where you need to land for some of the jumps, which could be okay except for the fact that failing some of those jumps causes you to fall waaay down and lose several screens of progress. I was working on getting one key and fell over and over...
It also didn't really feel like you had any decisions to make during boss rooms, for instance. It was more or less mash Shift while the boss flails around, maybe you die maybe you don't (but probably you do).
