The game is a deck-building roguelite set inside an aquarium. Players start each run with a school of guppies and use fish cards to summon companions, increase their numbers, and maintain a balance between predator and prey fish. During the day, players arrange the tank; at night, a boss emerges from the deep sea and attacks. Players repel the boss while collecting three egg fragments to escape. They can also enter an endless mode to face stronger opponents, including Poseidon. Coins earned from raising fish and defeating bosses can be spent at a shop on new fish and items. Before each run, players select permanent items and pets, but adding equipment raises a Depth Meter that unlocks new challenges. Difficulty options include a no-combat Zen mode and a boss rush. Through repeated runs, players unlock permanent upgrades, pets, and rare fish variations that can be kept in a virtual tank. Loopquarium is scheduled for release on PC via Steam and will support Japanese display.\u003c/p\u003e","blueskyPost":"Deck-building roguelite Loopquarium announced for PC.
