A pretty basic dungeon generation engine that randomly places the player and then does PUT SPACE SEEK and GO SEEK. Something like this needs a little more to be effective in a real game, though. Measures would need to be taken to speed it up (higher COMMANDS setting; non-reliance on the default player and a robot in the play area) and in general the areas created are cramped and uninteresting -- more space would need to be carved out (the passages would need to be longer and wider) and rooms would be added. With these modifications you'd probably end up with something like in Bombin' Dude... this is a decent effort, at least.
