The authors of Clair Obscur Expedition 33 have prepared various secrets. Players are gradually uncovering them, but it is possible that some things are still a mystery to players.
Recently, in a conversation with Eurogamer, game director Guillaume Broche stated:
"[There are still secrets in the game], but I don't want to reveal them, because then they will cease to be secrets. Perhaps they have already been found, but I have not heard anything about it."
Guillaume also noted that sometimes the "secrets" found by players are not actually secrets:
"The funny thing is that [fans] have discovered secrets that were not originally secrets. And we thought: \"Oh well. Let it be a secret!\"".
