I like the idea and the aesthetic of the graphics. The music also compliments art style and gameplay well. At first I had some trouble speeding up, but once I understood the timing, it was satisfying to start blitzing through sections of levels. It's also cool that it registers your best time and that your progress saves. I would be nice if there was a little more level variety (obstacles, boosts, etc.), but the different layouts of the walls sufficed. Cool game overall!
