Klonoa: The Door to Phantomile is a 2D Platformer developed and published by Namco. It released for the PS1 on March 13, 1998. A remake was also released for the Wii in 2008. I played the PS1 version on the Vita.
When the PlayStation released in 1995, pixels were out, and polygons were in. Everyone tried their hands at making a 3D platformer — from the sublime Spyro the Dragon to less intuitive games like Croc: Legend of the Gobbos. It was during this era that Namco decided to pioneer a new sort of game: a 2D platformer in a 3D environment.
