Such a fun game! I really enjoyed the mechanics and the puzzles got progressively more difficult. None of the levels felt repetitive and the music was really fun. Overall a very fun and challenging game, 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 :)
