Treasure Hunter is an arcade diving game where you control a diver connected to a boat by an air hose.

Your goal is simple: dive to the ocean floor, collect all the treasures and bring them back to the boat one by one. Each delivered treasure earns you 500 points. Once all treasures on the level are collected, you advance to the next one, which brings even more treasures and faster enemies.

You move the boat and diver left and right together using WASD or arrow keys. The diver also moves up and down independently. One important detail: the diver cannot stray too far from the boat horizontally, since the air hose has a limited reach.

The ocean is full of dangers. Fish and sharks patrol the water in horizontal paths. Crabs crawl along the sandy bottom. Octopuses move vertically, bouncing between the seabed and the surface. If any of them touches you or cuts your air hose, you lose a life and drop any treasure you were carrying. You start with 5 lives.

To defend yourself you have a speargun. Press Space to fire in the direction you are facing. Each shot costs one round of ammo, and you start each level with 5 shots. Hitting an enemy earns you 10 points and sends out a burst of green bubbles. Each level adds more enemies and they gradually get faster as you progress.

The game is saved automatically and you can continue from where you left off. Music and sound can be toggled at any time from the menu or with the M and N keys during gameplay. Press P to pause and Escape to return to the main menu.
