No single player

I love the boas game but get to play it so rarely. I was hoping, as the app advertises that there would be a single player mode. The closest the app comes to is a multi-player (on the same device mode). A single player adventure mode would be great, various difficulties, challenges and achievements would provide hours of individual Scotland Yard fun, and would make you a better player when actually playing with others. I hope that eventually this is added.
