> hjkl is not a reasonable default mapping for motion, for one it doesn't make it obvious that j is down and l is up since the keys are next to one another (which makes it a lot harder to memorise in the first place)

It's the same order as Dance Dance Revolution ;)

Also the same layout as the "cursor keys" (aka Protek Joystick) on the Sinclair machines - 5< 6v 7^ 8> (and ' would be the equivalent of 0 for fire.)
