About this game
Deep Blue Fantasy is a roguelike strategy adventure game set in an underwater world.
This is a distant future where the continent has sunken into the sea. Human, Merfolk, Leafkin, and Mechanoid all live together in the depths of the sea. You will become a 'lucky' adventurer, supported by a loan from the Jonathan Foundation and equipped with a submarine. From here, you embark on an adventure to explore the savage sea.
You will sail through procedurally generated underwater mazes, accumulating wealth by completing commissions, searching for treasures, trading goods, and defeating sea monsters. Once you repay the loan from the Jonathan Foundation, you will achieve true freedom.

Gameplay features
- Dice and Weapons: Different weapons require different ability dice to activate, which come from various crew members. Not only do you need to choose a sensible combination of weapons from the numerous ones encountered during your adventure, but you also need to assemble the perfect team to unleash powerful combat abilities and defeat enemies encountered along the way.
- Resources and Manpower: During your adventure, overloading your submarine with cargo will reduce its speed, while insufficient resources that cause crew attributes to decline will lead to unpredictable and adverse events. Balancing the advantages and disadvantages and making choices will be the key to the success or failure of your adventure.
- Exploration and Trading: You can explore every corner of the underwater maze, uncover buried treasures, and purchase low-priced goods from shops of different races to sell at a higher price in other areas. By choosing the right route and cargo, you can earn huge profits.
Gameplay overview
- 60 different Weapons and Equipment: Each weapon requires a different type of dice to activate, supporting multiple combinations and playstyles.
- A wide variety of Enemies: Unique enemies with different characteristics create various battlefields at different difficulty levels.
- 4 different types of Marine Terrain: the plain sea, the gorge sea, the glacier sea, and the volcanic sea, each with its own distinct landscape.
