Dull Grey is an award-winning visual novel developed by Sometimes You. It is a game about growing up, free will, and the pursuit of happiness. The story revolves around a mother and her son living in a retro-futuristic world controlled by the Progress-program. The game has won multiple awards, including the most innovative game of Games Cup 2019 and the 'Best Use of Multimedia' award in XYZZY Awards 2019.

The gameplay is based on a single choice that leads to different endings. You will be making the same choice repeatedly to decide the fate of the son - should he become a lamplighter or a tallyman? At first, it may seem that the situation leaves you no choice at all. But as you progress through the game, you will realize that your decision has a significant impact on the story's outcome. The game's visual style is reminiscent of Soviet graphics of the 20s and is inspired by the works of Strugatsky brothers, Dostoevsky, and Tarkovsky's movies.
