About Upstream Demo

Theirs is a journey defined by unmatched instinct, endless resilience, and the ambition of a creature that, for the sake of all generations yet to come, cannot afford to fail.

Play as a salmon journeying home in this challenging physics based platformer using only two buttons! Remember that on a voyage through innumerable obstacles and constant danger, it is your reaction to adversity that determines your success.

  • Swim and jump your way to the Mountain Spring as a spawning salmon using only a left and right button.

  • Traverse environments based on different ecosystems from the Pacific Northwest.

  • Experience an educational and emotional story about the life cycle of a salmon with a bit of encouragement along the way if your progress isn’t always forward (or up).

  • A cute salmon.

The reality of a spawning salmon is treacherous, so this will be a challenge for even the most seasoned platformers and speedrunners. Keep an eye out for alternative paths on your voyage!

A game with only two buttons can’t be that hard right? Please enjoy this demo of the first areas of Upstream!
