A video game takes some entertaining and philosophical wrong turns: the tennis player figure slides from the centre court into a parallel world and is robbed of his racket. The quirky “Pong” setting gradually evolves into the course of a desperate search for identity outside the rules of the game. The pathetic polygonal Roger Federer stumbles over glitches. Rowdy supporting characters offer first harassment, then help. The design, this undead relic from the past of games, is a subversive fellow player.
