@krakk8 It is a standard smartphone PIN (so 4 digits). As already said, upside down poster event date. The poster is upside down so maybe so must the date?

@Ben K Once you unlock it you can check an image and some texts.

@Wilco Yeah tried those too. Maybe it's bugged?

@Ryu I did think of that, that there might be numbers in the different colors of bricks. I did find an interaction that says the wall is actually wallpaper (wallpepper is what's in game if you want to fix it) but I cannot really find an actual clue:( Must be well hidden?

I think people would generally be hoping that an editor or translator will join in at some point to clean up the text. It's desperately needed.

Yeah the number on the book is for the safe deposit box. Still haven't figured out how to unlock the phone:( Maybe it's the time on the broken clock? Can't really read it though.
