I played with it for about an hour yesterday and had a nice time - mostly because it's easy - it feels like a strategy game that's aim at adults and is probably tricky - but basically, there aren't that many options on how to solve it, I manage to get through a level and a half in an hour, and I'm not very good in video games.
A nice part of it is that you can play it while doing other things like uploading pictures or talking on the phone.
