This is a fantastic game. I love the interpretation of the theme and the mechanic of adding to the level to be to able beat it! The block variety was fun and created some interesting dynamics.
This is more of a nitpick, but my only gripe is the platform lock-in control being the same as jump. While I like the simplicity of it being one button, I am so used to forgiving features like coyote time with jumping in other games that I would often place platforms when I was expecting to jump instead. Particularly with the bouncing platform.
That was my only issue though, everything else was top notch! I wanted to keep playing when it was time for me to stop. 10/10
