Upstream

Upstream is a physics-based platformer in which you play as a spawning salmon making the journey home to the Mountain Spring. Swim and jump using only the left and right buttons as you face obstacles and danger; your reactions to setbacks shape your progress.

The salmon's journey

Travel through environments based on the ecosystems of the Pacific Northwest. The game tells an educational and emotional story about the salmon life cycle, with encouragement when your progress is not always forward or upward. Alternative paths may also appear along the way.

Collect and explore

Collect salmonberries and salmon sense, and search for all the secret areas. Accessibility settings include Key Rebinding, Hold-to-Swim and Quicksave Mode. The journey is designed to challenge platformer players and speedrunners.
