Very interesting concept! It did take my quite some time to get used to the controls and in single player I got completely crushed. I liked all the small details, how for example the shadow moved around.
Over all a very nice 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 :)
