Free PC/Mac Game Alert
Tom Betts, one of the developers working on Sir, You Are Being Hunted at Big Robot, has released a experimental racing game that you can download on PC and Mac for free. Permutation Racer generates mathematically generates new tracks every time you play, acting a little like an abstract cross between WipeOut and ForeverDrive. You'll need nerves of steel and fast fingers to dodge hazards, exploit a powerful boost and beat the ever-decreasing time limit.
It's technically a prototype, but so far I've only encountered a single bug involving brightness and gamma.
Well worth a play if you're a couple of hours into a boring Thursday and possess mad Alt-Tab skills. Carl interviewed Tom Betts about Sir, You Are Being Hunted at Rezzed last year, which contains plenty of info about the Kickstarted Tweedpunk survival game.
