Super Mario Bros: Fast Foes is a hack of the original Super Mario Bros for the Nintendo Entertainment System that alters enemy behavior by increasing their speed. This adjustment affects power-ups and moving platforms, resulting in a more frenetic gameplay experience. Levels such as 2-2 and 6-2 are notably more challenging, enhancing the overall level of difficulty.
This hack is identical to the original game, but the enemies are slightly faster than normal. This includes the powerups and moving platforms, too. It's interesting how this physics tweak causes the 'feel' of certain levels to change - 2-2 and 6-2, for instance, seem much more hectic and hostile.
