echochrome is a puzzle game with a design inspired by the works of M.C. Escher. The gameplay is based around optical illusions, as the player must utilize five simple laws of perspective in order to join walkways, hide dangers and create paths in order to reach the "echoes", checkpoints in the game.
This implies that different actions are possible based on the camera perspective, which is changed when the player rotates the camera. The game's design encourages strategic thinking and problem-solving skills.
The PSP version of echochrome offers 105 levels with three game modes: Solo mode, Pair mode, and Others. The PlayStation store version, called echochrome Micro , has 56 levels with the same three game modes. Both versions have a built-in editor, allowing players to create and share their own puzzles.
The game also features online connectivity, with the option to download new puzzles from the PS3's network store. Players can access up to 300 user-generated puzzles, with older ones automatically replaced when the limit is reached.
