Hi. Forgive the very, very late reply. I haven't been very active here. There is indeed a lot of content missing, among other things. The game is in a much more polished state right now, but it's not finished. This game is my hobby, not my living, meaning development is slow.
As of right now, I'm not sure if I want to put resources into making another demo; my goal is to finish the game. Thank you for showing interest, though :)
