Not bad! Was fun to pick up speed and dodge through the obstacles, and it felt like there was a good ramp-up of difficulty in introducing new enemy types and such. Game core is pretty good, so I think the next step to take it polish it up a bit, mostly in regards to the HUD: the cartoony graphics are ok, but get rid of things like the bland font/text, decimal numbers, and other oddities to make it feel more cool and stylish. I feel like the main menu should show both the records and the powerup info at the same time side-by-side: no reason to hide one behind a button hidden on the side. Also, there's a rumbling/bubbling/crackling sound playing constantly that kinda hurts my ears: consider changing that to something more muted, if you must have a ambient sound.
