Diggys Adventure has never disappointed! This is a quest based game, with the basic plot of Doggy is searching for his father through different lands. But it is far from basic. There are logic puzzles, and challenges to keep you interested. There is also an amazing support staff for any questions or in app issues that may arise. You don't need to buy the in app purchases to have fun, because you earn gems by completing levels, however purchasing does sometimes provide a boost. I've adored every moment of having the game.
