The Avengers Space Cannon

You control a cannon at the bottom of the screen, aiming and firing colored bubbles upward. Your goal is to clear the field by matching three or more bubbles of the same color. Each shot counts. If your fired bubble doesn't create a match, you lose a heart. Lose all your hearts, and a new, threatening line of bubbles descends. The game moves at a steady, deliberate pace, demanding careful aim over quick reflexes. It feels like a quiet, focused puzzle where every shot needs to land just right.
