Urth is a unique game about a planet running away. Gameplay progresses through increasingly difficult levels as the player guides Urth to an uncertain future. The gaming experience provided by the levels is a combination of puzzle and abstract platforming. Escape mode features a large area populated by planets and stars: reflexes and timing are everything in this mode, as players try do distance themselves from the central star. Escape mode is a cross between maze and reaction games. The game was initially created as part of Ludum Dare 21.
