You can't create levels.
super mario brothers
On what level?
I prefer Mario 3 because of improved level design, challange, more fetures and gameplay
beat level 7a
You can't.
You have to get the diffrent exit to the level
rfghfghfgfg
You can't. It is impossible
no in new super Mario bros there is no level 0 there is only worlds like world 1,2,3,4,5,6,7,8
Beat the boss as a mini person
You have to get red flags on the level next to it.
On the last level of world 2 use tiny Mario to fight the monster and you can get to world 4 with tiny Mario
