Very nice game with a very important message! I really like the art style and mechanics of the game. By creating a high score system or how long you survived, you can compete with your friends. 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 :)
