As I Lay Dying is, as I am sure we all know, Faulkner's brilliant stream-of-consciousness novel set in the Gothic South in which the characters, at great length (well, with many long sentences at any rate) must transport the dead body of their mother to another town, where she wished to be buried -- as it slowly decays in the oppressive heat of Dixie.
As I Lay Dying the game does not (alas) feature the game analog of Faulkner's prose style, nor is it set in the Gothic South -- but it does have a relationship to the novel. In the first few minutes of the game, one of the characters falls from a cliff to his death. Your character, whose relationship to the dead person is unclear, decides that she can't just leave the corpse there to be eaten by ravens (which they will do if you let it lie). Your job is therefore to traverse ten platformer levels, carrying a corpse.
As in the novel, the corpse is a big problem. You can jump only very short distances holding it, so puzzles often involve leaving the corpse somewhere, and figuring out where you need to go unburdened and what you need to do to come back and get the corpse to the level end.
Naturally, every time you drop the corpse it decays a bit (with rather repulsive, if tiny-pixelled, bits flying away from it), and in many cases, ravens will pick at it if you stay away even momentarily. At the end of each level, the game tells you how badly the corpse is mangled at this point.
The actual gameplay is not likely to challenge serious platform players, but does contain enough of interest to carry you through; as is typical of platformers, new aspects are introduced over time (e.g., bridges that can support only your weight without the body), and the challenge does ramp up over time.
It's quite a tasty game, and the connection to Faulkner, if remote, does add a humorous frisson to the play.
