I have just completed the game, and it says to try Dark World. What is that and how do I get there?

1 Answer 1


The Dark World are just the same levels a few magnitudes more difficult.

To switch between Dark and Light World, you just have to press X on your gamepad or Shift on your keyboard in the level select screen (see an example on Wikia).

Note that the Dark World levels becomes available after you beat the corresponding Light World levels on A+. (Thx to shadow for pointing that out)


To clarify what I mean by "just the same levels a few magnitudes more difficult", I refer you to the blog of the creators of SMB. (The images are down somehow, so I linked to a web archived version.)

Why am I so hard

    "Same Levels" is a bit of a misnomer. They're similar, yes, but they can also be wildly different. May 27, 2013 at 23:04
  • @RavenDreamer With "Same Levels" I meant the layout of the level. The may be a few more saw blades or you might have to go through the level backwards, but the "room" is the same.

    Love that pic! :D however, sometimes it's not true. Sometimes, you are going backwards, or going to the original exit and back (Exploder and Not You Again in the Salt Factory are perfect examples) Sep 29, 2013 at 13:00

    You forgot to mention you need to A+ the level to unlock the respective dark version of it
