The Endless Fight of the Saint Isidore

You are captain of the embattled St. Isidore, target of every ne'er-do-well on the high seas. Prepare to fight!

Use W and D to move left and right and avoid attacks. Use A and D to move your cannonball up or down to hit enemies. Defeat enough enemies to proceed to the next battle. With each new battle, you gain an extra cannonball to your firepower, but your enemies grow more numerous as well.
