Ducks

Ducks is a free-to-play idle/clicker game built around collecting limited-edition ducks. The core design is explicitly ongoing by nature: every duck has a limited-time availability window that expires permanently, meaning new ducks must continuously cycle into the game to keep it running. The store description also advertises a duck-combining feature as "coming soon," indicating The Duck Company has additional mechanics still in development. The game's structure — time-limited collectibles, trading, selling, and rarity tiers — is consistent with a game designed to receive new content indefinitely rather than reach a finished state.
