The game fits the theme perfectly, you did a great job.
I'll suggest you some tweaks, that may improve your game.
- I felt the game a little confusing, maybe working a little bit more with the pallete would make you pick better colors;
- The background pattern makes the game even more confusing, you can try making it black!
- Do not make the music restart when you press the "restart" button;
- Make the music a little slower, with less BPM, that would make a great difference, and would make the game less "frantic".
Besides that, the game has that Flappy Bird feeling, a game with no "content" at all, just your score, and things like that, you could improve it by making a "global score" with players from all around the world.
