LOL. Renpy of that version did not support autofill.and most of the time the variables are misnomers or reused from something else, and have numbers tacked on in random parts, like:
which is especially heinous since the Renpy console does not autocomplete, so you always have to double check where the number is as you're typing.
It's like invisible serrated blades that cut you when you try to use the code (just like the UI), and it feels like it's by design. The guy went to extreme measures to make the code write only.
This is some Patrick Bateman shit.
