Proving the notion that few things breed creativity like constraint, the TWIFcomp - a challenge to write a work of interactive fiction in 140 characters or fewer (modulo whitespace) - just posted its sixty-one (61) entries online. In contrast, this year's Spring Thing, a themeless IF contest meant to provide an antipodal counterweight to October's annual IFComp, was cancelled due to receiving zero entries.
Many of the TWIFcomp games (particularly those programmed in Inform 7) can be played online; just follow the links. Don't expect to get much joy out of these little games if you're not already well acquainted with the medium; 140 characters means all punch and no context.
Speaking of playing IF online, Andrew Plotkin has just made all his games playable in-browser. This is possible by way of a modified version of Parchment, complemented with layers of handrolled, game-appropriate CSS he wrote to make them pretty.
I am very happy to see this happen. Interactive fiction needs to ditch its reliance on downloads and confusing third-party interpreter programs in order to reach all the people who ought to experience it, and it's great to see a major author of modern IF get this boulder rolling.
