It's been a couple years, so I'm not sure. Checking my notes, the core starting idea was "guy fucks himself in a genie induced time loop". And the genie being a dumbass and swapping places with him to get out of trouble was there really early on.
The "timelines don't line up exactly" twist shows up when I start writing page numbers with dialog, but before the notes on what the title should be. So I think I had a general story outline and started blocking out pages, then figured out the details as I wrote the dialog. May or may not have sketched myself into a corner and then patched my way out of it.
I was just wondering since the final girl is only drawn as a brunette here. If it was to get yourself out of a corner, im sure that was a big eureka moment haha
