100% save, goes in appdata.

And so nobody accuses me of actually 100%ing this, here's how I generated the save: (Way more fun than playing):
Cheatengine -> Dissect mono -> Assembly-Csharp (unity games always have their code here) -> GameData (looked likely, expanding it confirms) -> find instances of class -> copy the address of the one where true/false values are 0 and 1 instead of random numbers) -> add copied address manually as a byte (because the flags we care about are bools), plus an offset (like it says 'LasEndDie' is 13, so you would add addressYouFound+13) -> change the values to 1.
