Infinite Mario Bros

Infinite Mario Bros is a fangame and an infinite procedurally-generated platformer in the style of Super Mario Bros. 3 and Super Mario World. Starting from an overworld map, navigate a series of randomly-created platformer levels. Enemies include Koopas, Goombas, Piranha Plants, Bullet Bills, and more. Collect coins and power-ups and reach the end before the timer runs out. Beating the final castle continues the game on a new overworld map.
