I'm a bit new to Itch.io so forgive me if I'm doing something wrong but I purchased the game a day ago and what I've played so far is really good so far. My question is now that there's an update I have to pay again? If someone could please explain what if anything I'm doing wrong I would be appreciative. I've already tried using the link got in my email but that only let's me download up to version 0.12.
Until it becomes public you will have to pay again. Think of it like paying for early access...it's best to (if you are really dedicated to this game and want to play the new updates as they come out) subscribe to their patreon (which are small monthly payments) since, depending on how often they update, it's typically cheaper in the long run.
