If there was ever a game that begged to be framed and hung, it is Monument Valley. It is a beautiful piece of design, simple in form but visually sumptuous.

Presented as puzzle-platformer, Monument Valley sees the player guide protagonist Ida through a series of isometric levels, each delivered like an individual page of an ornate interactive picture book. Most centre on architectural structures that can be rotated to create illusions of perspective, freeing Ida to defy gravity and space in order to uncover each stage's secrets. It is brief, as so many mobile games are, but equally so rich in detail, playing through once will likely not be enough.
