  • Players who want forgiving platforming may hit a wall at the dangerous obstacle sections and physics-based movement.

Our take on Upstream

The bounce point arrives when two-button controls meet physics-based movement: the small input set does not remove the challenge, especially around dangerous obstacles, reversals, and alternative routes.

What is Upstream?

Upstream is a physics-based platformer about a salmon traveling toward the Mountain Spring to spawn.

Movement uses only left and right inputs for swimming and jumping through environments based on Pacific Northwest ecosystems. The route contains numerous obstacles, dangerous sections, alternative paths, secret areas, salmonberries, and salmon sense collectibles. The game presents an educational and emotional story about the salmon life cycle, with encouragement when progress reverses. Accessibility options include key rebinding, hold-to-swim, and Quicksave Mode. The challenge is aimed at experienced platformer players and speedrunners, while allowing completion at an individual pace.
