Stuart Madafiglio writes in with word that his story-driven cryptogram puzzler Stranger than Fiction has been released as a freely playable HTML5 game.

I don't often see games like this one. The core gameplay -- in which you decode short passages by switching letter placement -- requires you to use context and educated guesses in order to fill in the blanks within a larger story. It's great stuff, and it makes me wish that cipher-based gameplay was explored more frequently.
