I think for AI-generated websites, they tend to use a lot of emojis for almost everything. Also, they use colorful and bright colors.

If you'd like, I have an open source-game called Dungeon Maze (https://github.com/raihankr/dungeon-maze). It's a maze solving game with 2d pixel graphics. It was made with vanilla HTML, CSS, and JS. Utilizing the HTML canvas, I didn't use any game engine library in the development.

It looks like the website is not accessible.
