Hah! Here's the catch though. I'm finding it really hard to make proper collisions. What happens is I import the overworld image into MMF2. But this imports the whole image, meaning all the spaces Link can walk on too. So I have to make a "skeleton" file, deleting all the walkable tiles. It takes a long time to do. So if you're not up for mapping, another way to help is to take what's done so far and make a skeleton file out of it. This file would have two parts:
1) The outlines for houses, trees, etc that Link can't change.
2) The tiles that Link can walk over or change. Including the things he can pick up or cut away.
It's a time consuming task, but it's simple to do. If nobody's really up for it then all I can suggest is to make xcf files of everything we do so we can go back and delete the layers Link will be able to walk on.
