Hello, thank you for supporting me and for playing Room 310 Face to Face. I’ve checked the solution (Sandra's Memories) and the color sequence is correct. On the other hand, the Old Envelope file is a password-protected zip file; you’ll be able to open it with the information you find in the game. If you opened the door with a different combination, or if after following the clues in the game you still can’t unzip the file, please write to me at dareinteractive@outlook.com and I’ll try to sort it out.
