Very nice and simple game! I found it quite difficult but it was still a fun puzzle game. The fact that it was so difficult made me more inspired to try and get to the next level as I didn't want to admit defeat. Great 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 :)
