Thanks! Hopefully there won't be too long to wait

I'm fixing a couple of sound issues and so on now, but I don't have plans to include a blood particle option. Depending on what you want to remove, it might be fairly easy to customize in an option that deletes some of the trails/splats as they spawn.
The reaction to this has been great and I've really been happy with the help and pointers offered by the whole community. Trying it out on Vavoom was particularly valuable - it's impressive that it runs at all on an engine I didn't know about until last month!
I also found someone describing it as "a spiteful attempt to "clean up" Brutal Doom by tearing out about half the stuff and tossing themselves off over how much better they think they are" and was ready to get all offended about it but then realized that that description is 100% accurate, and have
put it at the top of the site as a ringing endorsement.
