About the game


In Underwater Diving, you are an underwater diver surrounded by aggressive fish and mines.
Collect the black corals to clean the idols.
Once all the idols have been cleaned, the exit will be free. But be careful, leaving a level is a one-way trip. So you have to be careful not to leave anything interesting behind either.
Explorers will be rewarded!
Collect energy bushes, which in addition to filling your energy gauge will increase its maximum. But above all find the precious red corals, the only way to increase the level of the diver and therefore all its characteristics.
If during the first levels you can and must both dodge and flee confrontations. You will have to become stronger to face the dangers and the immensity of the last levels. Labyrinthine levels that put your sense of direction to the test.

USP: The diver's energy represents both his life and his stamina, but also his oxygen.


  • USP: The diver's energy represents both his life and his stamina, but also his oxygen.

Designer's notes

The estimated time to finish the game is the time it takes me to finish it 100%.
So it will take you at least twice as long.
For the content of my games, I always prioritize quality over quantity.
