The gameplay was basic. I feel like there needs to be more obstacles or power ups to keep it interesting and increase replayability. Instead of a 1 hit kill, maybe you should make a health bar so the game is more forgiving (the tone of the music feels relaxed while the gameplay demanded you to dodge perfectly or you start over).
The music was upbeat and catchy. I play a lot of rhythm games and I'm disappointed that the music has no effect on the gameplay. Despite the word being in the title, there's no rhythm involved.
One thing I'd change is to draw a subtle line on the player's movement axis so they can see whether they'll hit an object before moving. It's a small quality of life change that will improve the gameplay.
Overall, good job with the game!
