echochrome

echochrome is an original puzzle game built on the principle of perspective and optical illusions inspired by the works of M. C. Escher and Roger Penrose's impossible staircases. The player controls a featureless human silhouette walking along staircases and platforms that seemingly cross and break apart nonsensically in space — but the key element of the game is rotating the camera, which lets paths that never actually connect appear joined from the player's point of view. What looks like an abyss becomes a passable bridge with a mere turn of the viewpoint, and conversely, a seemingly safe path can turn into a fall into nothingness the moment the player rotates the camera back to its original position.

The entire game runs on a black-and-white, minimalist engine without textures, which serves its purpose exactly — nothing should distract from the geometric puzzles and the play of perspective, with the environment made up of bare wireframes and flat surfaces alone. On higher levels the character also automatically loops back and retraces its path if it encounters itself from a previous attempt on the same level, further complicating the level design and forcing the player to think across several timelines at once, coordinating the movement of multiple copies of the same character. The musical accompaniment is spare, piano-based, and underscores the contemplative, almost meditative pace of play, which contrasts with the intellectual demands of the puzzles themselves.

echochrome fits among the experimental titles that Sony supported in the early years of the PlayStation Network as proof that its store could afford unconventional, purely conceptual games built around a single brilliant idea. Within the puzzle genre, it remains one of the most distinctive and most frequently cited examples of working with perspective in game design, even outside the circle of players who primarily follow retro PlayStation 3 titles, since its principle is cited in discussions of game design more broadly.

Why play it: For fans of puzzle games and anyone interested in the use of perspective in game design, this is one of the most distinctive and most frequently cited conceptual titles of the genre.
