Hiya! At some point I am going to update the public demo here. It was always meant to be free - the price tag was put on it because I had to do it to take part in itch.io bundles, which I have stopped doing ever since I realized how itch.io commerce system works and it was very misleading both for players and for myself. Your money is not wasted, tho. If you send me your invoice and how to contact you to cookiedraggy@gmail.com I will put you into a list of people to notify about Steam keys. When the game launches fully I will be in touch.
