Very fun puzzle game! I enjoyed the art style and the music. One thing you could add could be a restart button as I had to refresh the page to play the game again :D
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
