Super Mario Bros – World 7-1
Cannons everywhere. 7-1 is an overworld stage where Bullet Bill launchers are stacked two and three high, sometimes on both sides of a gap, and Piranha Plants fill the pipes in between. The timer is 400 seconds, which you will use.
The Bills travel in straight lines, so once you know their height you can plan around them: stomp the low ones, duck under the high ones, and never stand in line with a cannon while waiting for a plant to go back down.
Koopas walk between the launchers, and a kicked shell will not stop a Bill, but it will clear the Koopas ahead of you. The first row of question blocks includes a Super Mushroom; take it before the cannons start.
