Great game! I really liked the art style and music. The levels got progressively more difficult and none of them felt identical, overall a very fun and enjoyable game :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 :)
