About

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).
  • Satisfy your completionist side by collecting salmonberries and salmon sense, and by finding all the secret areas.
  • Enjoy the game at your own pace with accessibility settings like: Key Rebinding, Hold-to-Swim, and Quicksave Mode!
  • 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?
