Fun and challenging! I liked the style of the game and even if I died a lot it was fun cause I felt like I learnt more each time :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 :)
