I’m wondering when there will be a run for that category since nobody has done one yet.

Would you like to try? I am a little curious as to whether you'd get stymied for long by not having enough Gem Apples to unlock quests or not leveling up often enough to handle later quests or refill Vigor in time without tree upgrades, but I don't know anything about backing up save data to safely try it myself.

I would at least need a route first, and besides, I don’t know much about backing up save data either.

would happily give it a try if I had a capture card :(

I think you can still record without one as long as you can actually see the gameplay.
