Take control of the Blowfish and proceed throughout the depths of the
ocean. Be careful to avoid the many fish and other dangers you'll
encounter on your quest in the deep. Use your Puffer attack to prevent
yourself from sinking and to defeat enemies who are close by, and your
Spike shot to hit targets that are further away. Swim carefully but
don't let the time run out before you reach the goal at the end of each
stage. Every few stages a large boss lurks in wait, so conserve your
health and collect hearts whenever you can on your adventure as the
Spiky Blowfish!
