I really liked this game! It was nice that you could get upgrades and upgrade up your plane with magnets and shields. I also liked the retro vibe to the game and the music felt very fitting :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 :)
