The original game gave you option of two sets of adjustable keys for every command. I, for instance, prefer to use my right hand (arrows on keyboard) for swimming and contraction around objects, because my left hand (a,s,d,w) is nearly useless for doing circles/swimming. Is there any way to set both arrows and (a,s,d,w) for movement simultaneously? I find it tiring going to control keyboard and changing keys every five minutes.
