One player has reported that they cannot unlock letters from a certain princess who likes seahorses. Apparently by saying the correct password to the correct object, nothing happens. I have been unable to replicate this, so if this has happened to you, please let me know, and share as many details as you can!
I have! specifically the sɹǝqɯɐɥɔ ǝɥʇ uı ǝsɹoɥɐǝs ʇsɹıɟ the other one in the same room works, and I unlocked all of them other than that one in the same session, saved and reloaded it to try again and it's still not working :( browser is firefox, from my saved file, only been at this stage today but I've tried everything other than completely restarting the game.
