What makes Granny Smith so much fun is both the cute "Wallace and Gromit"-style graphics and with the excellent physics as you jump and zip-line through levels. There are three themed worlds to explore with 12 levels in each world, and you'll be faced with additional challenges (such as the need to throw baseballs) as you progress. When you reach the end of a level, the app shows you a retro-style replay with zoomed-in camera angles and occasional slow-motion effects. These smaller graphical details are what give the game a unique style that adds to the fun.
There are a couple of extra items you can unlock or purchase in the game. As you complete each of the first two worlds, you'll unlock additional characters to skate with. Though there are not any gameplay advantages to switching characters, you'll be able to play as Scruffy the dog or a heavyset man named Stanley if Granny gets too boring. You can also use coins you've collected to buy bonus items, such as a helmet for quicker recoveries from falls, and banana peels to slow down the thief. It is also possible to buy more coins with real money, but I was able to experiment with everything and have a fun time without buying coins.
For all its stylized beauty, Granny Smith has a couple of issues. The in-game sounds are not very impressive, especially in contrast to how great the game looks. It also has an annoying game mechanic in which missing certain jumps will send you into a pit that's impossible to get out of, and the game promptly starts you over from the beginning. While these aren't huge issues, they do take away from an otherwise unique and great-looking game.
Granny Smith is the type of game that's easy to overlook, but if people give it shot, they will not be disappointed. Beautiful graphics, solid physics, and the ability to pull off impressive flips and zip-line combinations will keep any gamer interested, and the cute stylized graphics make it all a bit more fun.
