Edit 2: I ended up asking on the Discord and got my answers. I'll leave this here for people who also have these questions: The Nutaku version has some minor alterations to conform to the site's standards, but is otherwise the same from what I understand, and it seems that updates can be downloaded freely on there if any more updates do come out.
-- Original comment --
Hey, played the Game Jam Demo a while back and enjoyed this. I've been getting a bunch of free Gold on Nutaku and I had nothing to spend it on so I checked their downloadable games section and saw that there's a version of this game on there, but the title is different?
I'm also unclear on what the full version of the game entails in the first place, so what're the differences between the Game Jam Demo, the full version here on Itch, and the version on Nutaku? If I buy it on Nutaku, can I still get future updates when they come out?
Edit: Just booted up the demo again and this is completely different from what I played at the time-- Somehow I had the full version by mistake, maybe? Either way, from looking at the comments I'm definitely interested in playing the updated version.
