Maybe you could consider restarting it and then use a proper game making tool instead of this piece of shit renpy which dates back to around 2010-2012 in its current version. You would also be able to implement many more cool features.Since we're going to have to restart the game, it would be nice to be able to choose if we want the LIs to work in the brothel or not (or which ones we want to and which ones we don't).
At the same time, please ditch Koikatu which blows no matter what you (try to) do.
