I loved the music and the main game mechanic. The minimalist style is also pretty nice. I do have some points for you to improve your game:
- Some of the jumps are almost impossible as you have to time it pixel perfect. Consider making the jumps more forgiving, except when there's a huge reward if you make it.
- The first level should be even more simple and quick to complete to teach the game mechanic.
- The player doesn't fall down when hitting the side of the "block switches". I got stuck when I jumped up and hit the side of the block instead of the bottom (see screenshot). In this case, I'd expect the character to drop back down or maybe even die.
Good work on the game and congrats on your first release on itch.io!
