Well this looks like a treat! I still have fun wolf3d memories using the sprite editor to add as much extra blood as possible and make the guards' pants fall off when you shot them, revealing a scribbly little dot around a sea of beige. Oh to be 12 again.
If this is in any way "closer to the original vision" or whatever of the original, having limits on graphics, sound, assets, etc. seems to have filtered out a ton of juvenile crapola in the original game.
I'm genuinely curious as to what possible corners of the burly-white-guy-runs-around-and-shoots-stuff* genre are left to explore. I'm serious; why not just play the last thirty games that were exactly like this? Slightly different guns? Slightly better/worse graphics? You can shoot nazi robots in this one as opposed to robot nazi zombies?
*"burly white guy" is not so much bad because of racism/sexism as because he is a personalityless generic stand in for the banal ideal self of the lowest common denominator of the gaming market.
