1 or 2 players
This is the hard version of the Super Mario Bros 1 map I created, and one of the hardest maps you will ever play. You start out at full power this time and only obtain potions along the way to rescuing the Princess. If you play with a friend you both can unlock the 2 player ending. If you hit all the flag levers you will gain access to another part of the ending. I have skinned this map to be visually similar to the NES.
