The game itself, the worlds additional puzzles are great, but unfortunately it is not a full version and you have to buy the game relatively quickly if you want to continue playing. But this I do not, because ever since I bought the predecessor, the game no longer works, and that is absolutely annoying. I do not want to experience again and leave it to remain the same the same thing! Pity is that the games for iPad will be charged with the full version and not on the Kindle! So it pays not to load the game on a Kindle! Sorry!
