Just when I think I’ve seen everything the day has to offer, a first-person puzzle game sidles into view, its levels resembling a series of tests. Perhaps there will be a novel method of interacting with the environment? Yes, there is! The clue is in the title, SWAP, for the player has the ability to take a thing and replace it with another thing that is somewhere else. One day there will be a game called WALK in which the player has technologically advanced boots that allow ambulation in any direction and are voiced by Morgan Freeman. SWAP reminds me of Q.U.B.E., superficially at least, and is available now for a penny short of seven pounds. There’s a trailer below.
