Klonoa: Door to Phantomile is a side-scrolling platform game viewed from a "2.5D" perspective. The player moves the protagonist, Klonoa, along a path in a two-dimensional fashion, but the game is rendered in three dimensions. This allows the path followed to curve and for the player to interact with objects outside of the path.
