I didn't known anything about For A Change when I started listening to the Clash of the Type-ins episode about it. I'm not a podcast person either, so it took a double coincidence for that to happen. But then when I heard "a high wall is not high to be measured in units of length, but of angle" it lodged itself in my head and I couldn't get it out. I just had to play this game.
It turned out to be more difficult than I had anticipated -- there's no chance I would have finished it without copious hints -- and shorter than I thought. The narrative is bare but intriguing. The mechanics are sometimes strange, sometimes obvious. Likewise the important objects are sometimes hidden, sometimes obvious. (And sometimes I missed the obvious solutions but nailed the strange ones immediately. Such is life.)
As a game on its own, I would give it three stars. Thanks to its unique writing and environment, I give it four stars. More people ought to experience this brief whirlwind of a game!
