About the game
Matter is a dreamlike, abstract platformer set in a world where gravity gives way and the surroundings keep reshaping themselves around the player. It offers a short, contemplative trip through a strange universe - roughly half an hour of calm parkour in which sound and matter respond to the player's every move. The game was developed by Uki Uki Lab and Concrete Games, and published by Uki Uki Lab in 2018.
