Cheat mode must be entered during play as follows:

Press and hold 'K', press and hold 'N', release 'K', press and hold 'A', release 'N', press and hold 'R', release 'A', press and hold 'F', release 'R', release 'F'.

You are now invulnerable to enemy fire. The cheat is disabled at the beginning of each new level and must be reentered to re-enable it.
