One reviewer said you don't play this game, but rather let it play you - and that's exactly what it does. It takes you on a breathtaking ride through a world - what world, exactly? At some point you're no longer sure whether it's really an alien world, or whether perhaps your world is the one that's faux. And when the ride is over, you can't help but look at what's around you a bit differently, if only for a passing moment. That's quite a feat.
Reminded me of Snerg's "Robot" for some reason. Perhaps the feeling of helplessness, both because of being taken on a ride with destination obviously well-defined but just as obviously not known, never fully, to you, and because of being trapped, stuck in substance, unmoving, slowed down, held down, observing but disabled. All in all - a very emotional piece, even if in a totally different sense than you usually mean when you say 'emotional'.
I realize that SpeedIFs tend to follow their own rules, but this one is utterly devoid of anything of interest. It feels like a mnemonic sentence that you make by filling in an absurd story between words you need to memorise. Maybe clever, maybe even funny, but rather not fun.
