Very nice game! It was quite difficult but fun. The different enemies had different behavior which was a nice touch. The art style felt fitting and over all the game was very enjoyable :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 :)
