About this game
This low-stress idle game keeps running while you are away, but it is not a numbers-go-up experience. Most of your time goes into keeping the water clean, feeding the inhabitants and petting the creatures. The free demo includes pond and river aquariums, while the open ocean is still locked; there are more than 200 creatures to find, each with a logbook entry. Filters, nets and spears are used to handle litter and trouble, and a dead fish leaves a blood trail that draws predators, so letting things slide has consequences. No account is required.
