This was such a fun game! I liked how the game was based around shadows and it worked so great for a puzzle game! This game has a lot of potential, can't wait to see what you com up with :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 :)
