Had a lot of fun with this, a really nice interpretation of the theme! I think the visuals and the blur effect are particularly cool. The level designs felt fun and varied and scaled up in difficulty nicely. Really great job!
To improve it further: I'd focus on polishing the jump mechanic. Very often I hit space but wouldn't jump at all causing a bunch of unfair deaths. I think the issue might be that the ball bounces, and isn't registering on the ground while in motion at times. The simplest way to solve this is to have a timer that tracks when you were last on the ground, and rather than needing it to be 0 to jump, you instead need it to be <0.1 seconds or something, just to give a short grace period.
I also couldn't get the game to run in Chrome for some reason? Worked perfectly in Firefox though!
