The 2D platformer is one of the oldest genres: the hero runs, jumps, clings to ledges, and dodges traps on his way to the end of the level. Today, the genre is experiencing a boom: some games emphasize precise and complex controls, others explore vast worlds, and still others emphasize a beautiful story and atmosphere.
Those labeled "Precision Platformers" are like Celeste and Super Meat Boy. Every jump in those games needs to be perfectly timed.
How is a 2D platformer different from a Metroidvania?In a typical platformer, you progress through levels one after another. In a Metroidvania, the entire world is one large, interconnected map, where you constantly return with new abilities.
Any of these games can be downloaded via torrent, repack, portable version, or GOG release.
