hi Petr, the game is meant to be played in black and white; it uses the different values of the ZX Spectrum colour palette to simulate different shades of gray when the output is set to b&w. So you can either turn colour saturation off in your monitor or go to Fuse settings and choose black and white tv. This is explained in the starting screen of the game but maybe it’s not too clear, so thanks for your feedback and let me know how you get on with the game!
