This was a really fun use of the theme, and I think there's a ton you could with this kind of level structure! The use of quick blurbs on each level with a new mechanic was a really efficient way to communicate the mechanics required for each stage. I definitely agree with a previous statement about a next level button and the movement indicators are a bit hard to see on the background. Those are really minor nitpicks that are easy to clean up though, nice work!
