Adam Saltsman, also known as Adam Atomic, also known as "the dude who made Canabalt," launched Hundreds, an iOS game co-created by Gasketball's Greg Wohlwend, on the App Store today. It's 40 percent off through January 10, currently running $3.
The goal of Hundreds is simple: build up at least 100 points between the shifting circles on-screen, though if a red, growing circle hits another object, you lose. If you're intrigued, play Wohlwend's original Flash version for free on Newgrounds. The iOS version of Hundreds is universal and adds new modes and mechanics.
