I just created a "minimal viable product" IDE for Cellspace. In effect: you can create your own games with cellular automata. I improved on the original user interface a lot: a level editor, load/save function, better rule editing, and a nicer tileset. Games are saved in Cellspace format (a human readable text format).

Press "Edit" at the bottom to edit the level, "Run" to run the game if you changed the level or the rules.

At the top you can select the sprite. The green square at the very left indicates "ignore", which can be used to ignore cell positions in a rule. Once you've selected a sprite, you can edit rules as well as the level. Currently you can only edit only one level and you cannot yet change the tile set. Other things I plan to add are win/lose conditions and more user input options.
