Would You Kindly Play Depict1?
(And I just realised after writing this that someone called Kieron already posted about this last year. Raaaargh. Oh well, you should still play it now if you didn't then. Old doesn't mean dead. Plus it means I don't have to take a new screenshot!)
Ooh, this is excellently devious. A Flash platform game from the developer of Snapshot that is... selective about the truth. I don't want to spoil too much, but its cleverness lies in two key fields: 1) needing to figure out the controls and mechanics for yourself 2) a narrator who demands your attention and trust but doesn't do much to earn it. And, despite his/her/its mendacity, it's hard not to like them.
We praise BioShockian twists in videogames, but it's remarkable how compelling a piece of game fiction can be if it declares its twist almost right away. Simple, smart, sadistic and a lovely wee treat of ingenuity. Go play Depict1 now. And work it out for yourself, for goodness' sake.
