App Store developers can be a rebellious kind -- we've already covered the story of a company shooting their price up to $40 just to show their customers how much they could be charging, and now, in response to an overly defensive trademark owner, developers on the store are putting the word "Edge" in their titles. Even high profile releases like the sequel to Eliss and the popular Canabalt are becoming Edgeliss and Canabedge. Critter Crunch becomes Critter Edge on their main page, and so on.

The story starts with a guy named Tim Langdell, who started a company a while back named Edge Games. Since he founded that company, he has mercilessly gone after any other game company who dares to use the word "edge" in their title, claiming that he has the trademark to any and all "edge"-related gaming. He's gone after EA's Mirror's Edge and a few other titles, but the App Store has been a prime target, where he simply contacts Apple, claims the app is in violation of his trademarks, and gets apps pulled without a problem. The latest target is a title called Killer Edge Racing by a company named PuzzleKings, and reportedly Langdell has gone so far as to trademark that name, despite the fact that the game using it has been around for years.

Hence the indie game developers' "edge-volution." They aren't actually renaming their games in the store, just showing off solidarity with other developers against what they see as Langdell's wrongdoing, and getting the word out about his actions against "edge" on the App Store.

The result of a 5-day coding session with the Flixel framwork, the free, web-based Canabalt quickly acquired fans and was soon ported to the iPhone. It's a fast-paced, great-looking game without complicated combinations or controls, and I can't stop playing.

Gameplay

The premise is this: Our hero's city is being destroyed by enormous, laser-wielding robots, leaving him with only one option.

Run.

Tap the screen and he starts off down the hallway of an office building and leaps through a window and onto the roof of the next building (and the next, and the next). You'll encounter obstacles along the way like boxes and bombs. Just tap the screen to jump over them. A quick tap executes a quick jump; press hand hold for a long leap. The longer you run, the faster he goes.

Some buildings are taller than others. Some collapse as you run across. Others are steel cranes. You must make split-second decisions about when to jump to make it onto the next building successfully. Don't bother making a mental map, as the order of buildings is random. Each time you play, it's different.

Look and feel

It's greyscale and blocky, but Canabalt looks great. Flocks of startled birds take flight as you run past them. Crumbling buildings shake and send chunks of concrete into the air. Huge spaceships rumble past and marauding robots can be seen wreaking havoc in the background.

The music sounds like a KMFDM album and is perfectly suited to the game's frantic pace.

Other goodies

You can compare your previous top score (measured in distance run before death) and brag on Twitter with the tap of a button.

Canabalt is just the type of game you want to have in your pocket. Uncomplicated, quick, playable with one hand and fun. It's perfect of a physician's waiting room, long train rides and so on. It's a great fit for the iPhone.
