This was a very interesting game! I got a really eerie vibe from it and the art style felt very fitting to a game like this. Considering this is a demo it's really great and I can't wait to play the full game :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 :)
