Sea Rescue!

In Sea Rescue! a submarine is stranded in a shark infested portion of the sea, and a rescue ship is sent. The crew must leave the submarine and swim up to the rescue ship, but they can only swim in a straight line and can't avoid the sharks. The rescue ship has an harpoon that can be used to kill the sharks, making the way up free for the crew.

The player controls both the submarine and the harpoon. By moving the stick left or right, the submarine and harpoon are positioned. By moving up, a crew member starts swimming up. The action button shoots the harpoon. Each crew member has 2 seconds to be released and swim up, or else the game is over. There are 75 crew members who have to be saved, but if just one is killed by the sharks, the game is over.
