Cell Runner is an arcade-style game for the Commodore 64 that was published in the September 1986 issue of the Compute's! Gazette. Taking place on a faraway, desolate planet, you play as an explorer who is just returning from the ruins of a former subterranean city. Unfortunately, the tunnel you used to get to the ruins has collapsed, and the only other way out is city's barely functioning mass transit system. You must climb up the remains of the transit system, but that is easier said than done as the cells that make up the system randomly open and close and you only have enough stamina to climb each level for 30 seconds.
nymx for the run takes up the challenge and climbs up all 40 levels and reaches the surface in record time.
