I Want To Live Forever: ImmorTall
Thanks to both Delirium and Andrew for tipping us off to ImmorTall by Evan Miller, a short, sad Flash game in which you (barely) control an invincible alien blob amidst one of humanity's less impressive moments. There's really not much more that can be said about this game in particular, since it's barely two minutes long, and about experiencing it for yourself. Other than the really smart use of music. Discordant notes create all the sounds necessary in a simple and affecting way. You can play it here. It's rather good.
