EnsenaSoft is a fairly well-known developer for mobile platforms. I’ve played some their games a few years back when I did a lot of travelling to and from work, and they have a nice catalogue of time wasters. You might want to check out their app store offerings for an idea of what kind of games they do (it is mostly puzzlers). They have now migrated to consoles with Miko Mole, a game that I know you will enjoy. Your kids will enjoy it too.
