Skipping story?
I just did what you said. We couldn’t beat the 3 knights 2 times in a row so I just went through, and i actually kinda regret it..i feel like I’m missing part of the story. plus the ending was super abrupt.
You’ll only miss out on the bossfight which in my opinion is kinda cool along with the music.
Other than that, the story itself kicks in where you can portal in via the backpiece-portal. So you’ll only miss out on the fight I’d say.
Using your phrasing: You pretty much skip the entire dungeon and get directly to the boss. And the boss is already in a miserable state.
After the bugfixing you should try to kill the Assault Knights and get to the Fight in the Drill. Its a really cool fight with nice mechanics, 3 different phases, and most importantly it’s not Brain AFK, you shouldn’t skip this when it’s available^^
You can just do the boss fight later, you aren’t actually locked out of doing it the normal way if you use the shortcut now.
