I'm throwing in the towel. I've replayed the game several times to see if I can finish it, but I've found it impossible. I don't know if I'm just really clumsy or if something is missing, but I can't seem to progress to the top floor... I've tried all the code variants I find in the bathrooms, but I can't seem to unlock any new rooms... If anyone has any suggestions or help, I'd appreciate it... Otherwise, I'll uninstall the game. Thanks!
