|Now here's some challenges. Several things that can be difficult to do.|
Let's start with this one, it's not too difficult. You must get to that level: the 1-D. Yes it's possible!
Really difficult ... you must go through all this level and without dying ... and the shortcuts are not allowed!
And here's a harder variant: the same thing, but for level 5-4!!
It's like the first challenge, but it's also different! This time, you must get to world -4!
You must go through level 3-3 without being hit by a hammer brother and without killing any of them with fire balls!
Usually, we go through level 6-2 by going through several pipes. However, there is a more difficult path that enables you to go through 6-2 without entering pipes.
