This is Portabliss, a column about downloadable games that can be played on the go. It's rare for an iPhone adaptation of a classic game to work out at all; rarer still for said adaptation to be preferable to the original. Jordan Mechner's faithful iOS/Android port of Karateka accomplishes this task handily, partly because of convenient portability, and partly because of nice new features.

But more than anything else, Karateka Classic succeeds because the original's controls weren't that great to begin with. Karateka is, when you get right down to it, a game about shuffling your feet up to your opponent, and then mashing on the kick buttons until he falls over. Like every other pre-Street Fighter 2 fighting game, attacks are slow and connecting depends not so much on timing or frame counting, but the will of some capricious computer god.
