Love it – Zombien Review

I love the story and system of checking but I got only halfway through and now I have to enter an authentication code to progress through a door in the story, and I keep typing things in and it says 'Don't just leave it blank! Type something!' I've been typing something for the past few days and it keeps giving me this message. Fix it or if there's a simple solution make it obvious. If it's obvious make it blatantly obvious
