The game includes a hidden level editor which allows the player to edit existing maps as well as create new maps. Maps used by the game are in the form of "scheme files" (.sch filename extension). The map editor is a simple interface, showing the map, dotted with different colors (0 to 9) to represent player spawns. A function called DENSITY chooses how "dense" the collection of breakable items is. The Powerup Manager chooses the list of powerups to be included, how often, whether they can be destroyed and what happens when two conflicting powers are picked (such as Bomb Spooge vs. Power Glove). The editor also sports a basic graphic interface: the player can switch between the "Green Acres" theme and a monochrome, patterned representation.
