Catch the cycler as it passes each planet. Odd levels carry crews from Earth to Mars. Send as many as you dare, then press Head Home. The even level must return every crew to Earth.

100 levels · 50 round trips. Level 1 circles in 9 seconds; Level 100 circles in 3 seconds. Empty-space mistaps waste fuel and cause wobble. A mistap with crew aboard strands them until you rescue them on the next pass.

Desktop level jump: Ctrl + Shift + two digits. Use 00 for Level 100.
