This is a rom hack of Super Mario Bros. called "The Mystery of Luigi" that has a lot more under the surface than what you see in the two levels of the game (literally) so you have to search everywhere in the game to discover all the little secrets. Also there's an impressive boss fight with a giant Bowser that actually exists in an NES game, MINDBLOWING! I've also included the game that it's parodying and it's been fully translated for English audiences so ENJOY! :)
