Gnop might be the most austere game you play all week, though not necessarily the simplest: Bit Battalion have (as you'll follow from the title) turned Pong on its head by giving you control of the ball, rather than the paddle, and wrapped it in light poetic metaphor.
The most surprising thing about it, though? That it took 38 years for someone to pull off such an obvious role reversal.
