Changes

Understand that the world is made up of pillars, and that the tiles are merely thin textures stretched out from the pillar's highest points. When you dig or drop dirt, all you do is adjust the height of the pillar (ie, a corner) you are standing nearest. When digging, all that matters are the corners. Tiles only matter when you use the "flatten" command, in which case the selected tile only decides which 4 corners (or pillars) should be compared to eachother each other and adjusted. Otherwise, ''forget about the tiles, only think about the corners''. Also, never forget that when digging and dropping dirt, it doesn't matter where you click, '''only where your feet are located'''.
