There is a place at the bottom of the sea where civilizations go to die.

For untold eons, the Grand Deep has drawn in the ruins of countless eras - a bounty which the Adventurer's Guild is eager to get their share of. As an experimental diving machine, it's up to you to face the overwhelming forces of the abyss, armed with only your bubbles, your bullets, and a lot of miscellaneous garbage.

Aquanaut is a compact twin-stick bullet hell action roguelike spanning 3 unique regions, each with its own obstacles, enemies, and challenges. The deeper you get, the more absurd your opposition becomes. Choose your items, and your strategy, wisely.

Build out your character with 60+ weird and powerful artifacts. Drop anchors on things you dislike, sprout eyes in the back of your skull, summon abominable eel gods to clear entire rooms of foes, and... boost your damage by 10%.

Face 20+ enemies and 6 menacing bosses who will push your build - and your skills - to their limits.

Prepare yourself, machine - the Deep awaits...
