Quads

You control a small ship at the bottom of the screen. Colored blocks fall from the top, and you shoot matching blocks up at them. The goal is to connect four blocks of the same color to form a square, which then disappears. If you don't clear them, the blocks pile up and eventually push a warning line downward; if that line reaches the bottom, the game ends. The pace starts slow but steadily increases, making you plan your shots more carefully as the screen fills. It feels like a calm but persistent test of your timing and spatial planning.
