TetherGeist

Embark on a treacherous pilgrimage to the Fount of Souls in this super-tight precision platformer. Help Mae master Spirit Flight and conquer hundreds of hand-crafted challenges across a punishing terrain. Awaken ancient tech, evade cursed spirits, and unlock the true power of the Fount of Souls!

Mae travels with Bao, her axolotl spirit, and the tether between them is the game's one mechanic: she projects her spirit out to a point and warps to it. Seven tether types, the Azae, change how that projection behaves, and each one opens movement the last did not allow, so the hundreds of screens are variations on a single idea rather than a pile of gimmicks. There is no combat and no skill tree, checkpoints are frequent, and timed challenges and hidden routes are there for players who want the speedrun. The story is a coming of age pilgrimage about community and difference.

TetherGeist began as a 48 hour entry to GMTK Jam 2021 that placed 10th of thousands, was funded on Kickstarter, and released on May 7, 2026 on Steam for Windows and Mac and on Nintendo Switch, from O. and Co. Games with Out of Space Games. It holds a Very Positive rating from 300 Steam reviews.
