I have been playing Diggy for nearly a year. I usually get bored when I hit a level that I can't get past, after many, many tries. I give up and delete the game. Diggy's game has an assortment of challenges, that require memory (or a note pad) and thinking. I really enjoy the special adventures that pop up at least once a month, they add variety. Thank you. Keep adding levels, I'm working my way up.
