Noticed that N-AY spell "CONTROL" with different letters having different background:
C: Sun (Most likely SOIUL)
O: Hole in Wall (Most likely N-AY herself)
N: Two hands (???)
T: Giant Eye (Maybe Scorch??)
R: Smile (Maybe Lantern or Cheater??)
O: Crying Eye (Most likely Crux for being one of only two characters having huge blank eyes (other being N-AY))
L: Pixels (Most likely Riot)
Not sure if these have correlations
with secrets, but if anyone tried and have results, please do reply.
