Defend the hero. Stop the snake.
COPU is a colorful, real-time puzzle-defense game. Match tiles, fire volleys up the columns, and hold the frontline before the snake reaches the robot.

One board. One frontline. No time to drift.
Every move matters. Build a match on the 7×7 board, send its color toward the snake, and use the moment to keep the hero safe.
Hit the right color
Choose the volley that can break through the approaching body of the snake.
Hold the line
Chain reactions, timing, and a little calm keep the robot out of reach.
