The issue with the blood was the only one I noticed, but it's understandable. Just an in-engine limit to decals, I assume. When I saw it, I actually anticipated Freeman would somehow acknowledge it and say "Woah, what the hell? Did the ground absorb it?" or something. The ground texture looks like it could be soft and squishy, so who knows. It's pretty unclear.
Good work, all around. I feel like that goes almost without saying but not acknowledging it in my introductory post seems wrong.
