I dig how Sprawl Zero rampages along the mirror's edge between world and corridor

Early on in my time with Sprawl Zero, I entered an otherwise forgettable room containing the absolute best puddle. Just, the Dark Souls of puddles: delicately embossed with oil around its rim, frighteningly clear in the centre. The kind of puddle you don't get in videogames nowadays, with their funky raytracing. An icy reverse render of the breezeblock walls and girdered ceiling, with no hint of the metal beneath, no transparency at all. Not a puddle, but a portal. The kind of surface from which you'd expect a gauzy hand to emerge, offering a magic sword. Or more plausibly in context, a fully loaded gauss rifle with a pop-out holographic display.
