This was really nice! At first glance this reminded me of the binding of Isaac (Probably just because of the viewpoint), but this puzzle game was so much fun and I really liked the music as well :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 :)
