Very nice game! This would be great for teaching someone about creating a game, I also liked the retro vibe to it and it was very enjoyable :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 :)
