Summary
Expand
is a 2D indie minimalist game in which you guide a pink square through a circular labyrinth that constantly rotates, unfolds and expands around you. Navigate through a world that can easily lift as well as harm you, keeping you disorientated and unfamiliar in your surroundings.
A world set in five stages, Expand offers an atmospheric experience of exploration, discovery and introspection through gameplay and compelling soundtrack designed to immerse you deeply into its allegorical themes.
Playing with a controller is highly recommended, but not essential.
