okay so now I'm playing Shadow of the Woolball, a cute(ish) themed Wolfenstein 3d inspired Doom mod.
like, it's VERY, VERY wolfenstein 3d. like, hugely. four weapons, flat, block layouts of levels, sideways opening doors (done quite well I might add!) and similar textures.
Though it's not just a copy of Wolf3d in Doom, its got its own features too! It's... kinda ridiculously fun? and you get to play as a hedgehog.
I say cute-ish because you're still shooting people XD
