Great little old-school style platformer which works surprising well on the iOS system.
I've seen some who complain about the graphics, but I tend to like that it has a slightly 'cartoon' feel, it is quite in character for the feel of the game.
Remember to keep an eye on the achievements as you get them, some are quite fun. Also, the game is iCloud enabled, which is the best way for any game on iOS to handle saving progress.
My room mate, she says that it feels like a 'different' version of 'Link' from the Zelda series of games. I can definitely see where she is coming from with that statement.
