Saw your post on reddit about this game and decided to check it out. I'm really surprised at how good I found it to be. I initially thought that the music blocks didn't make good sounds but as I went through the level it started to create a beat that sounded pretty good. And that was with me just placing blocks kinda randomly.
I didn't get too far but the only negative thing I can say is that there's no space between you dying and the game over screen popping up. It's pretty jarring.
