Hey!! Ahhhh, I'm very sorry!! Unfortunately, there's no way to skip directly to an arc because you'd bypass all the choices throughout the game, which would then make it so you wouldn't be able to get any of the epilogues once the finale is released (among who knows how many other possible errors it might create with skipped variables) 💦 You can skip through a good portion of the game fairly quickly though if you use either the CTRL or TAB key (CTRL will skip quickly so long as it's held down, and TAB will skip if you just click it once until you click it again). If you go into the settings and choose the option to "Skip Unseen Text," you'll be able to skip straight through even things that the game doesn't think you've read yet (which would be the case if you don't have your old persistent save data anymore):
I've also added the ability to skip cutscenes and credits that you've already seen with this update ---- however, this won't help you at least this first time, as the game won't register that you've seen them yet since your persistent data is gone alkdfjasd so I'm really sorry about that 🙏💦But at least if you need to go back again after this at any point, you'll be able to skip them then.
Hopefully this will help a bit 😭 I tested skipping through the entire game so far with the newly implemented credit skip option and it only took around 10 minutes to skip through the entire thing LOL Though in your case it will take a bit longer because you'll have to sit through the credits and the handful of cutscenes 💦
