Some puzzle games are about giving you simple rules and tools, then asking you to extrapolate how they'll apply to increasingly mind-bending scenarios. Others, like the recently-released Antichamber, ask you to rethink even the simplest preconceptions about how your world works. Antichamber's brightly colored, perspective-twisting world pairs time-worn platitudes and motivational clipart with puzzles that turn these proverbs on their heads — and make a mockery of anything you thought you knew about spatial reasoning. The game is normally $19.99, but it's $14.99 through Steam until February 6th. Still on the fence? You can read Polygon's review over here.
