There are a lot of games out there that start life "online" that eventually make their way to mobile platforms due to their popularity. One of those games is Gravity Guy from the folks at Miniclip, where you get run around defying all the laws physics and gravity while being chased by Gravity Troops in a fast paced side scroller that I find similar to the likes of Sonic the Hedgehog.
With multiplayer mode for up to four players built-in and two play modes to choose from, if side scrolling action is your thing then Gravity Guy is worth a look. The graphics are pretty awesome and Miniclip was mindful enough ensure gameplay lag was minimal, keeping the fast gameplay on level it should be.
