Is it a coincidence that the four passwords contain "fire" and "mother". Probably not. I wonder what this guy does in his spare time. No offense,or anything. I mean, I love the game and all.
That was surprisingly poignant. I was going to criticize the puzzle aspect for being too easy, but I think it worked well in that it didn't hamper the story, which was the real draw anyway. I did have a bit of trouble figuring out the very first one, so you could add some more description about water flowing before fire spreads and that you don't need to keep the sprinklers on to keep the fire from spreading past it. Other than that, great fun. Hokay, maybe you'll recognize this one, but I'm tired!
