Carry a drowned world's last light through a flooded voxel gate.
About Vesper: The Last Light
Vesper: The Last Light is a single-player adventure through a drowned voxel world, played in the browser with mouse and keyboard. You carry a lantern, and its light is everything at once: your health, your ammunition and your money. Every beam you fire spends the same meter that keeps you alive, so each fight is also a budget.
The first expedition, the Flooded Gate in the Nacre Expanse, asks you to restore three seals and earn your passage through a glowing portal. The route runs past a grove, a lighthouse and a temple, under cherry trees and a ringed planet. You jump across gaps, fire a beam of light and strike up close with a melee attack.
According to its maker, Kvickan, the game was made with GPT-6 Astra in Codex and shaped through playtesting and iteration, with procedural assets and licensed resources. The stated aim was a world you can explore, understand and finish rather than a scene that only looks impressive. The pacing follows it: readable spaces, one clear goal, a finish line. It runs on Three.js. It suits fans of short, atmospheric adventures.

I built it with GPT-6 Astra in Codex, shaping the game through implementation, playtesting and iteration. The project combines AI-assisted work, procedural assets and licensed resources. The goal was not just to generate a scene that looks impressive. It was to make a world you can actually explore, understand and finish—and care a little about along the way.
