Super Mario World/Ludwig's Castle

• Part 1
  • Bring a mushroom or a cape.
  • Wait for the Magi Koopas to hide and jump on it.
  • Dodge the first giant mace, then there are the two other ones that are much harder to avoid.
• If you don't already have a spare power-up, pick up the mushroom to the right of the door to Part 2.
• Part 2
  • As soon as you get through the door, run. There's a spiked ceiling rushing down. As soon as the ceiling is just above the ON switch, turn it OFF. Dodge the Thwomps and fireballs.
  • The ceiling will come down again, and the path between the lava pit and the safety zone is huge! Dash extra quickly!
• Part 3
  • This room is similar to Part 1 of Iggy's Castle, but this time you advance vertically.
  • Hit the Koopas on the fences. Move to the right for a "?" block with a cape (or a mushroom if you're small).
  • You will need to jump from one fence to another this time. However, you can still score a 1-Up by disrupting fence Koopas. Jump some more fences until you get to the final door.
• Part 4 (Ludwig's Room)
  • This room is two screens wide, so at first you won't see Ludwig.
  • Dodge his fire balls and jump on him. He'll retreat into his shell and jump.
  • If you're short on time, or if you don't like to waste time, make sure Ludwig doesn't go halfway offscreen. After he jumps, repeat the process 3 times until he is defeated.
