Deep Current

You are a Tide Ranger in the island world of Auroris. A strange force called the Deep Current reshapes the islands on every expedition. Lead a team of creatures across ten islands, rescue and capture new allies, find powerful relics, and reach the source of the Current on floor 100.

You won't win on your first try, and that's the point. Every run makes you stronger. Creatures you catch become permanent starters, eggs you find hatch back at your Sanctuary, and the rewards you earn buy upgrades that carry over to every future expedition.
