Inside a shipwrecked submarine, lays the heart of a strong-willed, perverse, recalcitrant, refractory, uncooperative, unmanageable, cross-grained, stiff-necked, military captain. Legend says it still beats, even after his death. To this day, no one has been able to come back from there alive, for the restless spirit of the Captain guards his home with all his might. Now, a brave explorer has set out to retrieve the heart, claiming the Captain was his great-grandfather. In this local multiplayer platformer, you may help the adventurer retrieve the heart and come back with his life, or defend your home from this intruder, taking the role of the ghost.
