Thanks for playing! Sorry you got stuck at the puzzle. I figured the "happy birthday to me" on the wall beneath the keypad combined with the glowing red bed with a date would be enough, but I should have set aside some time for playtesting with a test audience. Most people try 1974 as the code, despite that not being a birth date, rather a birth year. I considered adding a special text then hinting at 1974 being almost right but that she should look for the day and month, but ended up not doing it. I'll try to have some more in-world hints for my next puzzle!
