Super Mario Bros. Crossover is a Flash-based platforming game. Enemies such as Goombas, Koopa Troopas and Hammer Bros will prevent players from leveling up. Mario and Luigi can use Koopa bullets to take down enemies and take power from special blocks that serve to increase health, fireball or invincibility in a short period of time. Besides completing the level, players can also earn money and points, trying to get high scores.
