Whoa boy. I really want to like this game (I like most of the character designs, and the overall premise of corruption), but I can see why some things are a nightmare in this.
Full disclosure, I've tried rewriting this in renpy a few times (on and off). My latest attempt is going pretty well actually, but I'm not trying to fix any of the mistakes coding style choices this time around. I'm finding a *lot* of code duplication, which always makes fixing bugs a pain (e.g. time of day is not a variable in the game, so many screens are defined multiple times; once for each time of day).
I still have a long way to go, but what is the forum stance on fan rewrites?
