I'm a little late to the party, but I just finished playing Everybody Dies by Jim Munroe. It deserves all the praise it's received.

You start the game as Graham, a juvenile delinquent several years past juvenile. He's smoking outside of the grocery store where he works, using cart duty as an excuse to procrastinate. Before long Graham will be dead; but in this game, death is not necessarily an ending.

Great story and pitch-perfect implementation. The solution to the final puzzle is awesomely satisfying. The illustrations by Michael Cho are an excellent touch.
