The real definition of a platformer in my mind is a game where the most important aspect of the play is the movement of the character rather than the actions performed by the character.
In Mario for example, jumping, flying through space and all the rest of it is based on puzzles of the characters movement. Sonic is all about running and jumping as well.
Games like Contra and Castlevania are more 2D action games than platformers by my definition.
