AisleThis curious interactive fiction “Aisle” provides the player with only one turn in which to do something, offering the slimmest possible bit of choice. But by playing repeatedly, a set of possible worlds – with some consistencies and some contradictions – can be seen from a supermarket shopper’s re-lived instant. A Z-Machine interpreter (such as Windows Frotz 2000 or Zoom for Mac) is needed to run “Aisle.”
