Loved it :)
Game feels very well polished, although I am sure you have probably already considered this, but adding a duck to allow you to shoot the villagers coming up from down a slope might help, as from what I can tell the only way to deal with these are jump over or run back and shoot.
Another thing is maybe you should be able to shoot the villagers throwing objects? As you can in the original RE4? But that might make those enemies a bit too easy.
