Loopquarium is an aquarium roguelite where all fish play a role in shaping the ecosystem. Build a deck of fish to balance predators and prey, manage your tank, and survive boss incursions.

Predators hunt, generate resources, and fight back against danger, while prey support the ecosystem with unique abilities. Unlock new fish and items, experiment with builds, and discover unstoppable combinations each run. Avoid combat on Zen difficulty, relax in Virtual Tank mode, or descend into deeper waters where greater threats await.

Features:

• 60 fish types, 60 items and 14 bosses. All with unique behavior and abilities. (With more to come!)

• Endlessly Replayability: Strategize and build new combos every run

• Meta-progression: Become stronger as you unlock permanent upgrades and pets across runs

• Play at your pace: Difficulty ranges from Zen to Boss Rush

• Catch rare fish variants to be kept in the peaceful Virtual Tank mode

Create a starting deck and use your cards to summon a wide variety of fish. Start with a school of guppies and grow your population into a thriving habitat while maintaining balance in your ecosystem. Predators help fight bosses and generate gold, while prey support your tank with their special abilities.

As the day fades, increasingly powerful bosses rise from the depths and launch their assault. Every item gives you new tools to survive. Combine everything you’ve learned to turn the tide, summon fish that fight alongside you, harness the power of the currents, and exploit your enemy’s weaknesses.

Collect coins as you nurture your fish and repel bosses. Spend them wisely when the shop opens to hold the line. Upgrade your run with a wide array of items, each shifting the flow of your strategy. Catch or defeat enemies to earn card packs containing new fish to expand your deck.

Before each run, choose from a selection of persistent items and pets to shape your starting strategy. Be careful: every addition to your loadout increases your Depth Meter and unlocks greater challenges. Race to find the three egg pieces to escape, or push into Endless Mode and face deeper threats, including the likes of Poseidon. Branching paths introduce twists that can change everything…

Select Zen difficulty for a peaceful run. Catch fish, including rare variants, and add them to your collection. Earn coins to display prized fish and unlock upgrades for the Virtual Tank, where you can build your dream aquarium.
