You're welcome :) What really excited me were the multiplayer competitions: they have a ladder where your algorithm will be matched against other players, giving you a rank. You can start really simple (and be at the bottom of the ladder, but there's always someone below you!), and see it rise as you gradually improve it. Unfortunately it seems you now need to subscribe unlock those, but while I wish they went for another revenue system if it interests your kid it's definitively money well spent.
