Cool Game!
I liked the AI idea. It certainly helped. The guns and traps were good too.
I was kinda disappointed that Story Mode isn't really like a 'story'. I was expecting to move onto different areas and buildings, perhaps see other AI too (ones you don't have to pay for xD)
If there were other locations it would make it a bit trickier because you'd have to find where the exits are on the new buildings and cover them.
Also you should do the occasional power cut so you need the torch again to turn the fuse back on... Or different area's with only the torch. Yes, I like the torch idea, ok. Very cliche, but much more creepy!
I got to the point where I had covered the entire floor in a grid of bombs and chompy things and I just in the centre room and didn't need to do anything at all!
But it's deffinately kept me occupied, I'll give it an 8.
