Ya, it kills any tile interactivity(platforms, bushes and all that). Those functions would have to be rescripted.

edit: If you're going to be doing things from scratch, and you find type 0 very unorganized you might look into rearranging the tiles. Simply move things around to make more sense... it may be hard, but you may end up liking it. Personally I don't think it's worth it, and you wouldn't be able to move things like cliffs(the jumping tiles), and the bush and vase and stuff.
