The Devs Say...

Developed by Sailxe · Published by Sailxe

From the Devs

The Kepler-9 can't bring you back. AURA, the ship's AI, can only record you.

KEPLER ASCENT is a space platforming FPS for players who want to optimise every jump. One route per chapter, identical for everyone, every run: no luck, just you, the clock and the perfect line.

Movement to master

Grappling hook, wall run, rockets, orbits, saucers, trampolines, pendulums and ice
A readable game: nothing gets between you and a precise jump

Built for tryhards

12 chapters of 3 acts each, with a final chapter that closes AURA's story
Hundredth-of-a-second timer, 3-gate splits and a results screen
Bronze, Silver, Gold and AURA medals
Ghost of your best run
Instant one-press restart
Practice mode: respawn at the last gate, times not recorded
3 files to collect per chapter for 100%
Full run: every chapter back to back, total timer

Online too

Ranked duels with ELO rating and ranks
Battle royale: players are eliminated as the course advances
Friends matches via Steam invites

An AI watching you fall

AURA comments on your wins, and even more on your falls. "I saw the jump. You knew it wouldn't make it."

Go as far as you can.

AI disclosure	Kepler Ascent was made by an independent developer with the help of generative AI tools. AI was used to write part of the game's text (story and AURA's lines), to compose the music and create AURA's synthesized voice, to build some 3D models and cinematic sets (generated through scripts), and to produce the logo and artwork of this store page (rendered from the game's own models). All of this content was created ahead of time and reviewed by the developer. Nothing is generated by AI while you play.
