"In its simplest form, PRIOR is a 2D platformer by krangGames as well as being a Ludum Dare 19 entry. While there are abilities such as double jumping and the like that can be acquired, the main focus of the game is exploration and, more importantly, choice. In fact, there are three of them that lead to three different endings in the game. This, accompanied with notes found along your chosen path, not only provides a quasi-tutorial at times but also delve into the surprisingly rich story within the game's world. With regards to the notes, think "written audio diaries"."
