I'm a huge fan of puzzles, and this game has strategic ones, ones that make you use your brain, and you get to smash a lot of stuff!!!! Plus, I love games where there's a lot to do, and there sure is with Diggy!! However, I gave it only 4 stars because I wish it was easier to get gems, without having to spend real money. And I wish you could use the game "money" for more things, like buying gems!!!! Other than those issues, I'm obsessed!!!!
