Tenebris

Tenebris is a 2D platform endless-runner (procedurally generated) in which a cultist fails an invocation ritual and is now chased by Tenebris, a giant entity with the only purpose of killing him.
The gameplay features classic systems and mechanics of its genre, a player in an endless run for its life while avoiding obstacles using its abilities, the Dash and the Grapple.
