Sorry to hijack (if I figure out the answer to this one I'll post here!) but how did you get the door open at the first part of the gym (to this point)? I turned three switches blue but there's still something obstructing the hall. - edit, got it.
I technically have a thread for this but I think I'll leave it until I have my game run so here's my Rejuv fic too to join the bandwagon. https://archiveofourown.org/works/10976184
