Just a heads up - this site managed to choke WindowServer on MacOS 27/Safari long enough to trigger a watchdog reboot.

I never managed to load it and had to rush to kill its tab after the OS restarted and it began choking the machine again.

Takes forever to load, runs terribly and looks awful.

On iOS Safari:

Island Three could not start

Range consisting of offset and length are out of bounds

Reloading the page may help. A screenshot of this to @gruberbuilds on X helps fix it.

The weirdest experience in this must be to never know if you're walking uphill or downhill.

Where do the clouds come from? The AI?

Over half the people can't run it right or at all. Why not share some representative walkthrough videos?

This is crazy Claude built this.

I saw the landing page and I was like, "no way, Claude built that in real-time? Incredible." And then it loaded and it looked like a videogame from the 1990s. Pretty impressive for AI to have built it , and for something like that to run in the browser, but it's so clunky and ugly that I couldn't try it for more than a few seconds.

I hate it when products promise something so breathtaking in posters or trailers that is utterly detached from how the products looks or works. I might have tried it longer had that landing page not set this high of an expectation.

Overselling a product may getting you a higher conversion rate up to a point, but it will only hurt you and crater the rest of the funnel.

Neat. I enjoyed the NPCs chatting about life onboard.

I've had an idea to build something similar - or more specifically, a game in this form, since I saw Eric Bruneton's Rendezvous With Rama video, now about 15 years ago.

Never did hand code it, even though I gained a lot of the skills and work in gamedev. This makes me feel time is running out to implement it with some of the unique twists I had in mind that become apparent with something like this ...

This is a website, not an O'Neill cylinder, and I can't walk around it.
