Our games are pretty close in difficulty. We do recommend Blitzkrieg for new players. Our biggest challenge is The Cure. It's Mine is somewhere in between. The Cure is a one room game. The others use multiple spaces and have areas you can't get to right away.
You stay in one room the whole time. You'll probably need most of the hour to solve it. I actually think all the rooms were about the same difficulty and enjoyed them all greatly.
