I think next update should be the last one, patreon have a newer version, that version has the entire story (including nanami week)
but the game is about to be done, I'm doing everything I can this april.
If you're wondering if buying will get you newest updates, yeah of course, but patreons will have it first, the lastest update will be exlusive to patreon for the time being until I end development (which will be fairly soon, between this and next month)it will go from 31 to 38 scenes with the next update
