About Artemis Descent
A short arcade game about a spacecraft's return to Earth, inspired, the entrant says, by the Artemis moon mission. The pitch: dodge obstacles to guide a spaceship back to Earth. The game's text tells you to keep the heat shield facing down and into the fire and to survive instability, heat and debris; warnings such as “SHIELD SLIPPING”, “WRONG SIDE EXPOSED” and “HULL DAMAGE RISING” flash when it goes wrong, and a good run ends with the parachute deployed, a splashdown and the crew surviving reentry. It was made with Phaser for the Cursor Vibe Jam 2026, whose rules required at least 90% of each game's code to be written by AI; the official submission lists Codex as the tool. It finished 793rd of 945 entries. Free in the browser on the developer's site; it plays with the arrow keys or A/D, or by holding the left or right side of the screen.

Verification notes: Tool (Codex), engine (Phaser), genre (Arcade), pitch, inspiration (“The Artemis moon mission”) and the multiplayer (No) and mobile (Yes) flags from the entrant's answers in the official Vibe Jam 2026 games data (submitted 26 Apr 2026, 10:05 UTC; final rank 793 of 945 entries, no award), re-read on 5 Nov 2026; rule 3 on the jam page requires at least 90% AI-written code. Developer: the X profile @ryanws_dev (display name Ryan Stolliker, location San Francisco) lists ryanws.tech, a portfolio headed Ryan Stolliker that gives San Francisco, California and links back to the same X profile; the game sits on that domain. Team size is not stated. Game text from the game's script; the game was not played. The entrant answered Yes to mobile; the script has touch controls (hold the left or right side of the screen, per the in-game hint “Hold left/right side or use A/D to correct.”), though mobile play was not tested. No calls to AI services were found in the game's script. The release date is not stated; the jam submission is dated 26 Apr 2026.
