Keyboard and rules
- Editing: arrow keys move the cursor, Enter or Space applies the tool, W / S / G / X pick a tool, 1–6 pick a robot.
- Playing: 1–6 pick a robot, arrow keys plan its move (. to wait), Enter steps everyone at once, U undoes.
- Watching: Space plays or pauses, left and right arrows step through time.
