Here's Carto editing a map with the Pixelspace tileset. It's a better image, since the PNG format doesn't lose the colors like GIF does. Pixelspace as a project is dead, but I like the tileset (for the most part).

This is a screenshot of Pixelspace, a game under development.

Mario 3, back from the dead. It's a slightly revamped tileset, and shows off the multiple-layer feature.

This shot is from the "testgame" map. Testgame is the scrolling test program.

Here's the tile selection mode shot from the "testgame" tileset.

Commander Keen, with a fresh new look. The background tiles are rather ugly, but other than that it's the same old Keen. This shot displays the attribute mode (which is what all those 0's are).
