The port to 8088 is really interesting. I can't find the minimum system requirements for the original Wolf 3D, but didn't it require a 386? (I'm pretty sure it used a 32 bit DOS extender).
The dithering (on a VGA card and modern LCD) sort of makes it hard to view; an EGA port might be interesting as 16 colours might be enough to make it workable without dithering. Although if they're using 2x2 blocks for dithering, they'd be effectively cutting the number of "pixels" to render by a factor of four, and that might make it viable.
However... there is a little known game that id Software did release that would run on an 8088. It's called Catacomb 3-D[1]. It was basically Wolfenstein with goblins and skeletons. Pretty sure that engine went on to become Wolf3d.
Despite the Wikipedia page saying it runs on a EGA I had a CGA monitor and was running it. Thinking I might be losing my mind I downloaded the source code on archive.org[2] and sure enough there is reference to CGA code all over the place.
You need to decrease the window size a bit if want it to be playable on a 286, though. At full size, I tend to get a headache.
Germany has unbanned Wolfenstein in 2019 :)

The README in the project talks about "8088 support" being added, but the only thing I see in the commit log is the replacement of a stray 286 assembler directive.
Shift-by-immediate-value was introduced with the 80186 (and became broadly available with the 80286). https://en.wikipedia.org/wiki/Intel_80186#cite_ref-6
