I have a hypothetical way to access the story mode early.
Because it was mentioned in the "Seed of your pants" video that the only thing locking the content was a single True/False variable, a tool like cheat engine could be used to easily edit the variable and access the content. The hardest part would be the trail and error trying to find the right variable to edit.
I'm not going to try this personally because I have other things to do, but if yall want to have a sneak peak the option is these.
Live long and prosper.
