Mind Fuck is game for two players inspired by a game called Mind Chess.
Mind Chess plays a bit like Mind Fuck, so here's a quick explanation..

Or to quote auntie pixelante who unsurprisingly explains her own game much better..
"
mind fuck is an experimental game for two players, one using the left shift key and the other using the right shift key. the goal is to collect 400 points. a counter in the middle of the screen keeps increasing, and whichever player presses her key first gets those points added to her total. you want to press the key before your opponent does, but you also want to hold out as long as possible before doing so. read your opponent, intimidate her, distract her, press your button right before she’s about to press hers."
