Aisle

What a wonderfully successful experimental piece. As has been well documented, the game ends after your first action, but the results are myriad and compelling. I played late into the evening, and it was some time before the true story hidden in the simple dynamic finally revealed itself (and after I'd already thought I'd figured it out). Beneath an illusory simplicity is a very funny, scary, and ultimately moving game -- if you're willing to try as many possibilities as you can. It's weirdly cathartic to be presented with a recurring moment in time in which you can try whatever action (within reason) is at hand.
Also, there are some amusing twists based on IF conventions that are quite unexpected and funny.
Literary and fun: what more could one ask for?
