Canabalt dev seeks fan feedback on challenge mode

Let Semi Secret know what you think of a challenge mode for popular platformer Canabalt.

Adam Atomic tweeted an image of a few challenge sketches on a white board.

"Some vague, mysterious Canabalt ideas. What do you think?" the tweet asks.

Canabalt is a popular "one button action game" in which players control a running figure. It first saw major success on iOS but is also available on Android - in the current Humble Bundle, no less - and as of a recent update, on the PlayStation Network.
