[Description]
Get to the end of the level by jumping over various gaps and avoiding the enemies on his way, stairs in the level, as well as jumping boards. There are also pipes along the way, some of which Bros can enter to visit various secret coin rooms before returning to the level, a bit further ahead than when he left.

Enemies include Little Goombas, Koopa Troopas, Buzzy Beetles, Koopa Paratroopas, Bullet Bills, Hammer Brothers, and leaping Cheep-cheeps. All these enemies can be defeated when Bros jumps on them. Koopa Troopas and Buzzy Beetles cower in their shell when jumped on, which Bros can kick to defeat other enemies with. Other enemies include Piranha Plants, and the Spiny-throwing Lakitus, and Bros has to either shoot fireballs at them or just avoid them

Bros can get special power-ups out of blocks or, uncommonly, bricks. Most of the ?s in which Bros can find these items are visible, but some are hidden and only become visible when Bros hits them from beneath.
