Free (itch) version goes until the end of the beach, up until the train station.
Patreon version goes few levels into the city (after the train level).
Itch version will stop content wise at its current point but get system/bug fix updates.
We'll always update bug fixes and system updates (as I write this, the project is loading up to finish up refactoring the Sex system, which would be included in the demo version update) And we'll always update with information as well. The only thing itch version will not have is new content. But updates to systems/bug fixes will continue.
