The 4 maps, hmm, they all play almost the same... Kind of boring due to creeper camp spots and such.
Needs more music.
About GvH36, it doesn't feel addictive like some other maps. Don't ask me how they can become addictive, but it's kind of boring like GvH00. Besides, that theme is heavily overused.
One main reason that I could come with is that it fits eternal blood's theme perfectly, whereas it doesn't really feel like GvH.
I would actually like to see more comments with brutal honesty. If there's something you don't like, please post about it here!
The 4 maps that are way too similar, there's nothing unique about it, its all the same theme, gameplay, etc. Heck, it's made by the same person as far as I know. I mean there's no problem for making 4 maps for the same wad but, you can't make every single map the same theme. GvH needs to be more diverse.
That map that looked like the hallways of some AoW map was just, plain terrible, it's ripped, boring, etc. Not to mention that the whole map is plain bland. AoW isn't really praised for its details.
