RetroSouls has just released its latest ZX Spectrum title, PiglyFlag, a charmingly decent monochrome puzzle adventure that tackles a question some may has pondered: what happens to our favourite pixels when the screen goes dark? According to creator Denis Grachev, these digital companions end up trapped all alone in the pitch black, missing us terribly. In this stylish monochrome game, players must step in to rescue a deeply frightened little piglet, guiding and pushing them safely toward each level's exit while dodging a host of treacherous creatures known as the Brymlis.
