Adjacency is an abstract puzzle game about colors and shapes with a minimalist philosophy.
You spread colors to adjacent tiles through various mechanisms to achieve the correct pattern. Although the concept is simple, the puzzles soon become challenging. Adjacency features 60 puzzles and is aimed toward both casual and perfectionist players alike.
The game features ambient sounds and music by the talented Haley De Boom, who you can read more about here. The music subtly transforms as the player progresses through the puzzles.
