Beyond the various oddities and nonsensical moments, at its heart it's a game about American progress and the corpses it leaves in its wake, a pensive Wizard of Oz-like point-and-click adventure through a country whose yellow brick road is built on futile hopes and unanswered prayers. That sense of impermanence is such a crucial part of Kentucky Route Zero, more so now that it's a complete work with a full arc and definitive ending. Even when the game's at its most peaceful and gentle, it never quite feels stable or permanent, like everything good, bad, strange, or affecting that happens in the next five acts could disappear into the darkness at any moment. The game knocks you off-kilter in the first seconds, placing you in the last fading glow of sunlight before nightfall on a threadbare stretch of road. That Kentucky Route Zero's very first image is a gas station at twilight is apt. Depending on the road, it can be the only point of light for miles and miles, and beyond is nothing but an infinite abyss of curves and strange noises in between you and your destination. There's always something deeply unnerving about a gas station at night.
