Klonoa

Klonoa 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. The game is divided into levels called "Visions", where the player progresses by following a path with defeatable computer-controlled enemies and puzzles that must be solved. (wikipedia.org)
