It just about guarantees 100% success rate with about 5 mins of practice. Everyone hates losing the run with 20 seconds left.
I guess we should decide on what categories/rules are what. I'm not deadset on the categories that exist so far, just thought I'd get something up there. Right now I've got:
100% Messenger Transcend any%
I suppose 100% would include unlocking the 3 Messengers (A/B/C), All Sigils, Stars, and Items unlocked (fan/block/connector/etc). Only thing I'm not sure on is how to "end" the run. Messenger ending has highest requirements, but you don't really "unlock" anything new just by ending that way. Same with transcending, you use up the sigils you've found, but don't otherwise do anything besides solve another puzzle. So, I guess the fastest ending would be to Eternalize. Thoughts?
Messenger ending category is low% I guess, since you can skip the red sigils for Nexus Floor 2.
Transcend ending would be the same, low% skipping Floor 2 sigils again, as well as any sigils needed for the Platform unlock.
any% I guess we can start off by setting it to "the fastest way you can end the game with one of the 3 endings, Eternalize, Transcend, or Messenger.
