In the public version, I did not obtain the password to unlock the first chapter of the "Demon Within" crossover storyline during the prologue of the "Shelter" crossover event.
We used to have a bug related to tablets but it's been fixed and both Demons Within and Shelter have the same code for that now.
What model of tablet are you using?
Did you download the android version of Shelter from my itch page or from some other source? Did you play both Shelter and Demons Within on android? (because the code only shows on android)
I'm asking if you played both on android, because your Demons Within screenshot has the android ui icons on top of the screen and Shelter's screenshot doesn't, so I'd like to make sure.
