The path changes from stage to stage, so read it first and pick your spot
Sea animal friends fight with you and each one works differently
A sawfish crosses the row with the most enemies
An otter throws a stone that bounces off the walls
A penguin dives straight down from above

Between stages you upgrade your weapons and crew at home
