Feign, Ian Snyder's moody, disorientating maze game, is a marvel of minimalism and inversion. Dialling everything down to a bare minimum and intermittently switching between dark and light textures, it transforms what would otherwise be a broadly simple affair into an atmospheric exercise in pleasant bewilderment.
Nominally, this free browser game is about navigating around the near-monochrome maze to collect nine 'bodies', which is the kind of terminology that immediately adds a tastefully sinister air to the proceedings.
Really, it's about screwing with your spatial awareness, using the unsure borders of its washed-out world to turn simple puzzles into more complex ones - and frustrating the hell out of you when you come to track down the ninth and final body. It's convoluted and a little cruel, but I'm sure you'll find assistance in the comments below all too soon.
Those of you who do work it out/already know: please flag your tips up with suitably screamy SPOILER ALERTS first, ta.
Oh, and Feign features a sombrely giddying soundtrack by someone called Brother Android, who it appears is something of a respected personage in such fields.
In case you can't be bothered to navigate this word-maze back to the link at the start, here it is again.
Thanks, Michael Cook.
