Really nice game! I liked the art style and music, it gave me proper retro vibes. The puzzles were fun and I did enjoy this a lot :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 :)
