I found myself sifting through the level buidling code for The Crawl and came up with a few new ideas.
First thing I did though was rehaul how the editor looks. Its much cleaner now and I fixed up some troubling bugs.Second thing I did was make it so that like tiles connect both physically and shading wise, meaning no more having each individual tile be a little pop up. Instead they all join together and sink where they differ.Third was adding the option for a tile to be either sunken or dented. In the image below, provided with and without textures to best demostrate what is happening, I made the brick based tiles dented out and the dirt tiles sunken in.In theory I could now have puddles and the likes. Yay puddles.

It's moments like that I wish I knew some words stronger than "awesome".
That top screenshot looks quite good.
I wish I could comment, but I'm on a crappy CRT right now.
