Such a fun puzzle game! I really liked how you progressively made it more difficult and the levels were all fun and challenging. The music was really nice and chill to listen too and I like the simple art style. Would love to see more levels, keep up the good work :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 :)
