Super Mario Bros – World 5-3

  • Level type: Treetop / athletic
  • Time limit: 300

1-3 with cannons. The tree tops and moving platforms are laid out the way they were in world 1, but Bullet Bills now fly across the gaps at platform height, and the timer is 300 seconds.

The Bills come from off screen, which means you cannot see the cannon that fired them. Listen for the shot, then decide: stomp if the Bill is level with your feet, duck under if it is higher, jump if it is lower. On a narrow platform, ducking is usually safer than jumping.

Red Koopas are still on the wider trees. Everything else is the same platform course as before, so if you cleared 1-3 comfortably, the only new skill here is reading the Bills.
