Apparently there's a sort of carnival fortune-telling machine thing that tells you whether you are to be "multiplied" or "equalised" -- whatever that means, and everyone who gets a letter with an addition sign has to go consult it, wherever they are. The one recurring character is a classic private investigator who's looking into what all of this even is.
I'm not clear as to what all this even is.
It's a story told with an impressive economy of words. When one person resolves not to go, and the next vignette shows her there anyway, her partner standing behind her with a baseball bat, we can fill in the blanks. Likewise with the private investigator's ongoing quest. But we can't fill in ALL the gaps. We're never told what it means to be "multiplied" or "equalised", for one thing, so we have no idea why it's significant.
It's also not clear how our interaction affects the story. I get the impression that it matters which of three identical blank cards we feed into the machine each time we see it, but that's basically a crap shoot. I believe that in my replay, the same card yielded a different result at one point, so perhaps it doesn't matter -- there's no actual agency here. In which case, why play at all?
This has all the weirdness of Groover's usual work, but none of the decadence. As a breakfast, it's chocolate pudding: nice flavour, but I'm not sure it really counts as breakfast.
