 The majority of the game takes place in these levels, with the player traversing the stage by running, jumping, flying, swimming, and dodging or defeating enemies.Players start with a certain number of lives and may gain additional lives by picking up green spotted 1-Up mushrooms hidden in bricks, or by collecting 100 coins, defeating several enemies in a row with a Koopa shell, or bouncing on enemies successively without touching the ground.Mario and Luigi lose a life if they take damage while small, fall into lava or off the bottom of the screen, or run out of time.
