Learn the terminal by exploring a world made of folders: catch bashlings, battle tamers and earn badges with real commands. There is also a terminal version.
Save your progress with a save code. It lets you carry on later,
here in the browser or in the terminal game. Press Copy save code (or type
code) and keep it somewhere safe; copy a new one after you make progress, since
each code holds your game as it was when you copied it. To continue, type load
and paste it. (This browser also saves your game as you play, until its browsing data is
cleared.)
