You steer the HALDANE-4 submersible as Harlan Webb, descending into a cavity under the Ross Ice Shelf to reach 1,325 meters and bring back a sample. The cave walls, your craft and the cable trailing back up to the surface appear on an old terminal screen. You thrust through the dark, turn the view to find passages that only show from some angles, and can cut your lamp and engine to hide. The creator says a run takes 10 to 15 minutes, and the game won Most Original at Vibe Jam 2026. Works on phones and computers, though the creator recommends a computer and headphones.
How the creator made it
The creator says they built HALDANE-4 over seven days, with Claude writing the code and Cursor serving as the editor and handling quick fixes. They set themselves constraints of a small download, text-only graphics and procedural caves and sound, with an ElevenLabs voice-over for the radio. Claude synthesized the music and effects with Web Audio, and the creator adjusted the mix and did the final mastering. The creator says they tested the game and made the commits themselves at every iteration.
