Some perspective.

Remember the good old days when computer games were written by just one guy who sat in his bedroom programmed the game, made some programmer art, recorded some sounds and then packaged and sold the whole thing together as a game.

io is such a game and is made by one such guy from his bedroom, no less. io is modeled after those classic side-scrollers, punctuated with a stealth twist and advanced graphics. io is priced at $13.
