I'M STILL HERE you can make a top level in the post
the game start thing is just explaining what's happened so that you can do your own thing
Added some clarifications
ALSO, ANOTHER QUICK BUT IMPORTANT NOTE
This game operates heavily on dream logic. Many characters should be operating under the assumption that they totally do have all of their memories! The AU kind of fills in the gaps with BS.
So for example if one AU'd character goes up to another and is like SO YOU HAVE AMNESIA RIGHT?? your character is welcome to be like "what. no? i remember everything"
