The first one that really blew me away was the demo of Superhot[0].

Try these out, they're made in Unreal and compiled to WASM.

Note that the second link (space game) will take a bit longer to load, as there's no loading screen.

There was one I saw on here a few weeks ago that excited me but I don't have time to dig through my bookmarks at the moment.

Of course there's the original Diablo also.

And don't forget all of the DOSBox stuff on Archive.
