As I wrote in my first review, there are now 5 Stars. The error was quickly corrected, it was not long and I was an update appears. Downloaded and finally working the game. The game is great, even for smaller children .. We have already the first part. My son loves the game, after a short time he understood the principle and could play independently .. In parents' area you can switch between light and hard, so that again, new challenges can be created, or even multiple player profiles are created (great for siblings).
