It's very cool, but I think two issues keep this from being truly delightful. First of all, it doesn't really feel like a computer, little things like typing "dir" in the command line could be a great little interaction, but it's not supported. I'd try to make it more fun to use and not just pretty to look at.

The other thing is, I think the portfolio doesn't really match the quality of the website you vibe coded. This is actually a pretty bad sign that your own work is not as good as something you can do with AI (human assisted or not). The website is pretty high quality, so browsing through extremely simple assets just feels out of place.

Overall it's a good project.
