What's the difference between the demo and the official?
Viewing post in A Town Uncovered - Adult Visual Novel (NSFW) comments
the demo is free and is stuck at 0.28,
the official has the up to date versions yet it costs money.
if I were you I would save your money till they finish the game, it's buggy super buggy being a big renpy project.
But in my opinion I don't ever think they will finish the game cuz most games on this site flop after halfway though
