First of all, LOVE the music! The game was very interesting and I didn't really understand the grouping part but looking through the comments I see that you're working on it :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 :)
