The game is quite simple, but surprisingly a lot of fun! As you stated, you made it in 2 days but I think some time could have been spend in making the boundaries for the height you are allowed to be in. Mainly because that's the way your game applies to the theme, and it feels missing without actually being able to see the border. A checkpoint indication or visual would also have been a great / simple addition.
For a game that is mostly white, I actually really like the visuals, especially the vibrant background. It complements the much simpler colors in front quite well, and am actually really curious how you made this.
The gameplay also feels decently smooth!
