doomed
by entering the seed "uh oh" the world generates as normal, there is no music (music boxes do nothing), the player spawns with the usual tools and the "strange note",
the strange note's tooltip reads "see you at the finish line", the strange note has no use, the strange note cannot be researched in journey mode
the lunar event text is altered, first pillar "you're filled with unease", second pillar "something isn't right", third pillar "you swear you saw someone in the distance", final pillar (bright red text) "you've doomed us all"
after the usual 1 minute wait the players screen goes black and the picture of red's face appears (you know the one), the world is then deleted.
