Remarks:
Jim Waterman submitted this to Andy Jenkinson's CSSCGC 2022 as an April fool's gag. The backstory is that this is a Lambda demake of Andy's 48K 'Rubik Code' (which bore unintentional similarities to Jim's 'Casio MG-777 Games'), submitted to Jim Waterman's CSSCGC 2021, when the roles were reversed.
