Another approach used in some graphical games with programming elements is to present the player with a command line interface to issue orders via a domain-specific language to direct objects within the game, allowing the player to reissue commands as the situation changes rather than crafting a pre-made program. Games like "Quadrilateral Cowboy" and "Duskers" have the user command several small robotic creatures in tandem through the language of code to reach a certain goal. "Hackmud" presents the player with a simulated mainframe interface through which they issue commands to progress forward.
