Some games are about winning. This one is about wandering. A lone duck on an endless ocean. Sharks, dolphins, and other creatures drift past — get too close, and your trip ends there. So you don't fight. You don't rush. You just steer around, and keep going. Hold to stop. Release to surge ahead. Repeat. The rhythm becomes a kind of meditation. A small, steady ritual in a loud world. No notifications. No leaderboards shouting at you. Just the water. Duck's Trip doesn't ask you to be better. It just asks you to keep going.
