Simple but challenging puzzle mechanic that works smoothly. Great color choices and easy to understand gameplay too. 

This is amazing! If you added more levels I'd definitely test them out. I do think a consistent background would make more sense though. Also, if you're not playing fullscreen,  on the final level part map intersects with the little itch.io info boxes in the top right corner. Instead of registering clicks on the game, it registers the clicks on those boxes, so you have to go fullscreen to complete it. It's not a big deal, but it is a little annoying until you remember about fullscreen.

Game fits the theme well, gets very difficult on the last few levels. Music fits really nicely, mechanics are simple to understand and clean to work with. Enjoyable game.

I really love puzzle games, and I really love this one too! Good one!
