Constructive criticism please?
I tried making some tilesets for a "game" I started writing (currently only consists of walking around). There's dirt, mudstone (which is what I've decided to call the generic gray stone), and peridotite (the green one). I mostly want to know how worried I should be about making the big blobs of the same type look better. They currently have 4 different variations of each sprite to try to avoid a visible grid, and have separate sprites for bordering air. The border tiles (the dirt ones are visible) are perhaps a tad bit rectangular, but I do want them to have corners where normal tiles would so that I don't have to make my collision detection fancier or have the player floating on air. Also I might want to eventually add dirt borders similar to the borders with air, for, say, two different types of rocks meeting. Please ignore the box pretending to be a player :).
