I tried editing the savegame and it didn't work but I think the game ended very fast, I haven't even bought a 2nd camera....As for the save game sharing issues, I saw people mentioning it was a new thing added to Renpy.
Though I don't know if Aleksey actually doesn't want saves being edited/shared or it was just overlooked.
It's already been posted here I think, but the game just ending like that will be changed in a future update. It can be gotten around with mods for now.
What are these mods you are talking about and where do I find them? Looks like all the mods on page 1 is for the older version?
