The Atari 8-bit machine version, at first sight, shows notable differences. Although graphics dimensions are same that the rest of versions, it is remarkable their monochromatic screens. It is true that Spectrum version was also two-colored; however, in this case the two colors are used in the whole screen. The main effect is that the horn or the handbag cannot be darkened (for example) and they simply don't appear until they are caught. This happen with the main characters, too.
The really prominent aspect is the sound. In our humble opinion, it leaves a wonderful flavor to arcade machine of the 80's. This doesn't mean that it is the version with the better sound, simply that there is a remarkable difference when comparing to the others.
