Booty Diver is a retro arcade action game based on Atari/Nintendo games of yesteryear. The game take's a lot of inspiration from the unreleased Atari 2600 title Aquaventure. As the titular "Diver" you traverse 5 different regions of the ocean seeking out sunken treasure (Booty) guarded by King Poseidon ,and his guardians.
These dives will not be a simple splash and grab though as you must manage a limited air supply while battling Poseidon's minions which include Starfish, Octopi, and etc. Do not threat though as the "Diver" has a few means to defend himself with his short range diver's knife ,and his trusty harpoon gun.
