probably the map is hidden. click the gear in the upper-right of the game. the settings popup will display. one of the tabs is for layout. make sure that "hide grinders when automated" is not clicked.
That's something I'd really love to do! It'd have to wait until PlinkyPlinky II: Plinkagon Heights, though. Much of this game was developed before I knew anything about writing code, so a feature like user-generated levels is somewhat prohibitively difficult. I'm really glad you enjoyed playing it though <3
