Minesweeper and freecell are basic system functionality. Putting these available only via a store^W package manager makes as much sense as replacing the UI with a flat interface suited for tablets and phones.
Actually I didn't notice the package manager. It's a bit slow to install, and after installing I get ZIP file error when trying to run dosbox. There are a billion minesweeper clones that likely are trivial to integrate.
But it's not a clone of Windows 95; it's its own thing, which I think is kind of the point. Whether or not to include a Minesweeper clone is totally up to the author.
The fact that you can run an actual copy of Windows 95 inside it and run Minesweeper there is way more impressive to me (and it worked fine for me, for what it's worth).
The entire design and name is retro. Without it, I don't think the HN crowd would have been so enthusiastic. The only really new thing is the package manager, which is another step in running an OS under a browser.
* There are existing examples of JS x86 emulation or compiling stuff to WebAssembly, e.g. [0] let you run Windows 2000 in a browser over a decade ago.
