Really nice art style! The game was quite difficult as you had to jump on a very specific point to be able to jump over the boxes, but I liked the challenge. I liked how you had the music continue even if you died, that way the music didn't restart every time and it didn't feel as frustrating. 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 :)
