Reuben Levine writes Sometimes simple fun is the best kind of fun. A game like Mr. Runner 2: The Masks by Zing Games is the perfect example of this. The original Mr. Runner was a hit, and the sequel seeks to both capitalize and improve upon that. If you're looking to get some arcade-style gaming in quick bursts on your iPhone, Mr. Runner 2 is one of many fine choices. It's got the features, character, and zaniness to carve its own path on the iOS market.
