Some games take years. This one took a weekend — and a frontier AI model as a pair programmer. On Thursday, developer u/HugoDzz posted a video to r/ClaudeAI titled 'Made a "Destroy Any Website" stickman game': a destruction sandbox where you type in any website URL and the page itself becomes the level, ready to be shot to pieces by a tiny stick figure.

The thread exploded. Within a day it had pulled nearly 2,500 upvotes and more than 150 comments at 92% upvoted — and the developer says the video had already gone viral on X a few days earlier. The top of the thread did something unusual for a hype cycle: it got nostalgic first, and asked hard questions second.

The game: type an address, break everything#

The premise is exactly what it says on the tin. The game, live at destroy.spritefusion.com under the Sprite Fusion banner, greets you with a single instruction: "Type an address, break everything." Paste in a URL and the site's page is converted into a 2D level. Then you run, jump, flip, fly, aim, and shoot your way through it — stick figure versus the DOM.

The controls read like a love letter to the Flash era: A/D to run, Space or W to jump (tap again to flip, hold to fly), mouse to aim and shoot, right-click for a grenade, number keys to swap weapons — plus a drone you can dive-bomb into the scenery. Matches end with a "Website destroyed" tally and a destruction percentage. There is real multiplayer, with named players and a host who picks the target site, and — perhaps the savviest touch — an embed badge so any website owner can put a "destroy this website" button on their own page and let visitors smash it.

A weekend build, with an unusually honest AI credit#

What makes this more than a novelty is how it was made — and how candid the developer is about it. HugoDzz, a TypeScript developer, says he built the game over the previous weekend: a raw engine and renderer written from scratch in TypeScript on Canvas 2D, multiplayer on Cloudflare Durable Objects, hosting on Cloudflare Workers. No game engine, no framework doing the heavy lifting.

Claude Opus 5.5 was the pair programmer. According to the post, the model helped brainstorm the architecture and the technical compromises, wrote implementations that kept design patterns consistent across the codebase, and sat in on the artistic side too — live-tweaking explosion effects and particles until they felt right. But the credit comes with a caveat the AI-hype threads usually skip: the developer says he had to steer Opus 5.5 "more than I expected" to keep it on the rails. When a commenter jokingly called him a vibe coder, his reply was the thread's best line: "The vibe coder here is in fact a coder."

That distinction matters. The recent wave of "AI built this" demos — see our earlier look at the one-prompt Opus 5.5 music video — often obscures how much human judgment sits behind the output. Here the human is telling you exactly where the model helped and where it needed a leash: architecture sparring partner, pattern enforcer, effects tweaker — while the engine, the netcode, and the design stayed human.

The thread: pure nostalgia, plus one fair objection#

The top comment, with 468 upvotes, set the tone in six words: "this is so painfully 2001. I love it." The thread immediately turned into a reunion — one highly-voted commenter remembered a site that did something similar "like 15 years ago," another declared "the original creators would be proud," a nod to the Animator vs. Animation stick-figure wars that defined early web video.

And then came the fair objection. "Except that this IS a rehashed game," wrote one commenter. "This was a viral thing like 20 years ago." Another was blunter: "You didn't make it." It is a reasonable challenge — destroy-the-webpage toys are genuinely old — and the developer answered it the only honest way: he had posted the game on X days earlier, where it had already gone super viral, which is probably where the skeptics had seen it. The game itself demonstrably works — the site is live, the multiplayer lobbies fill — so the argument was never really about whether he built it. It was about whether the idea is new. The thread's verdict, judging by the score: a beloved old idea, rebuilt well enough to deserve a second life.

What to watch#

  • The pair-programming pattern. This is the emerging template for serious AI-assisted builds: an experienced developer, a frontier model as sparring partner, and a shippable multiplayer game in a weekend. Watch for more "built with" posts that name exactly what the model did — and what it couldn't.
  • The X spillover. The developer says the demo already went viral on X before Reddit found it. If the embed badges catch on, "destroy this website" buttons could start popping up across the web as a novelty widget — the rare game mechanic that is also distribution.
  • The rehash debate. Every AI-built retro revival now faces the same question: is it a copy or a cover version? The threads that answer it well — like this one — are becoming the genre's real review section.
