Changes

*Other games manage to get the elements (background and sprites) in different colours : yet still mono-coloured themselves. this  This greatly increase the games quality and understandability of the environment despite being still inferior to real 2bpp graphics in 3 or 4 colours for Sprites or backgrounds, and this still enable some Amstrad CPC's specificity over the ZX spectrum : the lack of colour clashes that goes so well with Isometric variations.
