Decided to try something different with these, so I made them have a bit of a border around. Yeah, hard to really add a lot of variety with 8 square pixel tiles, but I tried to come up with as many formations as I could, and also added narrow tube tiles for areas where one would use something like a morphball instead of being able to walk around.

Comes in four colors, and has all the special tiles at the bottom. Personally, I use gray for charted, unvisited land, blue for charted and visited, red for extreme temperature, and green for uncharted, like Metroid Fusion does.
