Tetris in PostScript: A Real-time Game in Under 600 Lines

A developer has implemented a real-time Tetris game using PostScript, remarkably achieving it with only 600 lines of code (around 10KB) and 69 distinct operators. The game features arrow and spacebar controls, increasing game speed, 7 tetrominoes, high scores, and a Nintendo-style scoring system. It runs in GhostView on macOS and draws some implementation inspiration from MeatFighter.
