Well, despite having googled for at least two hours regarding this subject, I haven't been able to find anything. I've checked the documentation on this site and Zzzophar and it seems I'm out of luck.

Here's what I need help with:

I tried to take one of the levels in World 1 (Level 2) and change it from a hilly to a plains level. Somehow, that screwed things up. I don't have any idea how. If there's someone here who can explain how this works or provide some documentation, that would be great.

I also need some tips on pointers inside the level, like how they work and how to edit and use them.
