@o1eh - Well this is most unfortunate.

In summary, as you exited the room, the alarm had attracted the attention of 2 zombies. You managed to beat them both but whilst you were fighting, another zombie attacked you. You won again... only to be attacked by another zombie. The alarm really did cause you some issues. Whilst testing the code, you died numerous times but the time that I ran it for real, you survived. Somehow.

Unfortunately, the comment wasn't just pruned due to size, if was completely removed. But you're now stood in the corridor so if you reply "{B}", my guess is that you'll try to open a locked door and the game will work.... just without the excitement and near death that Steemit deemed too long to share with you 😔
