 Although reviewers were less than impressed with the graphics on lower @-@ end systems such as the ZX Spectrum , the colours and large detailed sprites on the higher @-@ end platforms won their acclaim . The animation of the characters also captured their attention . Tommy Nash of Your Sinclair hailed it as " first class " , while Paul <unk> of Zzap ! 64 called the sprites " beautifully defined " and " realistically animated " . Similar accolades were given by other reviewers . The staff of The Games Machine were " constantly [ amazed ] " at the designs of the monsters in the game .
