You control a marker in Qix , which must draw rectangles and other objects to claim your territory. The speed at which you draw these shapes affects your score: slower draws earn more points. Once a shape is drawn, it turns into its corresponding color, signifying that the territory has been claimed.
The game requires attention to two main threats: Qix, colored lines that move across the screen, and Sparks, which travel along the borders and any shapes you've drawn. Additionally, The Fuse moves along the line you're drawing, adding an extra layer of challenge. Your goal is to claim enough territory before these obstacles catch up with you.
