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?
