Deep Sea Diver

Your job is to probe the sea floor and gather all the treasure you can find. Of course, it won't be a cake walk. Along the way you'll face man-eating sharks, killer clams and deadly baby guppies. Armed with an unlimited supply of spears, you must slice your way through 10 levels of formidable underwater foes.

You have to keep an eye on your air gauge. If you aren't able to pick up the air that's dropped from above, you'll die of suffocation.

You'll find three different types of treasure chests. One rewards you with 100 points, one is a smart bomb that kills every enemy on the screen and the other is a trap that blows up and kills you. There are small differences between the chests that will give clues about their contents. It's up to you to figure out what those differences are.
