Let me start by saying that I think this is a brilliant game; but there is plenty of room to expand. I think a smart thing to do would be to add more rooms which you could explore, and to thicken the plot with some of the 'other survivors' that the AI mentioned.
Maybe I have a mind for these sort of puzzles, but I found them to be really easy. An expansion would be very much appreciated, for I really, really like this game. That, and a save option.
