First of all: this is really fun, but I did suck at it.
Controls are really fun but I had a very hard time trying to do more advanced tricks, not a criticism, just so you know where my skill level is roughly at. I want to try playing this with a controller sometime, I found it difficult to change between wasd and different buttons used for tricks. Think for me personally a controller probably mitigates that.
Keep working, more tracks, music, perhaps some cosmetic options for the cute character. Very well done.
