Opus 5.5 builds a browser CS surf parkour game in one session
The author built a CS surf-style parkour game in the browser with Opus 5.5 across eight steps, including a speed meter, leaderboard and ghost replays, then shipped it as a single index.html.
AAA studios spend years and $100Ms on a game, and this CS surf run was built in a browser tab with Opus 5.5 in one session here's the run, stage by stage: stage 1/8 · write GAME.md first: the feeling, the loop, the numbers and the rules stage 2/8 · build movement only, with F1 sliders for speed, gravity and air control stage 3/8 · one map with 8 neon ramps over a void, a timer and a finish gate stage 4/8 · let Opus open the tab, play it and fix what feels wrong before you see it stage 5/8 · add the juice, so the speed meter climbs past 2,800 u/s and the camera leans into every ramp stage 6/8 · a live board that tells every runner "you are #37 of 1,204" stage 7/8 · ghosts of the top runners racing the same map next to you stage 8/8 · ship one index.html behind one link, so your friends click instead of downloading the rule that keeps it alive is simple: copy the feeling of CS surf, never its maps, names or sounds the full run with every prompt is in the article below ↓
