Bait Master

With your arrow keys, navigate your ship to collect bait at the island and search for creatures to catch it with.

When you find their shadows lurking below the surface, touch them to see if they take the bait. If they do, you catch them - and then they become your new bait for the next type of creature.

Feed the sea spirits to the north, southwest, and southeast. Each will give you a key, and when you collect them all the Sea God itself will appear. Feed it to win!
