Super fun, I played the brutal version of it and that definitely made it a lot better since it added cut enemies. It was very different than the original two, I think I prefer 64 over both. Unmaykr was sick, the maps were pretty challenging. I wish they were more bigger open space ones and the map puzzles weren't too confusing or rage inducing. I recommended for sure, plus it's free on archive.org with GZDoom
