As much as I love the game, S ranking it is starting to make me despise parts of it. There's some things they really should have fixed:
-Stomp move. It shouldn't have been context sensitive.
-I think this is common in some Japanese action games but I don't know how many (several Capcom games does it at least): when you get hit the enemies won't attack you for X amount of seconds (probably 1-2 seconds), at all. Bloodrayne should have had this. Getting hit and losing points because of it is a bad enough penalty. If you mistime a "fast get up" it feels very unfair to get hit multiple times in a row because enemies attack you as soon as you get up again.
And for me personally, I think the platforming should either have been removed or simplified greatly. I'm playing the game for the combat, not for the platforming.
For the sake of my own sanity, I probably should just give up on S ranking it. Mission 8 is just insane. Not only is it difficult to do all the platforming without dying, it's also difficult to get the no damage bonuses in the fights. I just haven't figured out how to effectively do combat while there's those bomb/star ladies around.
Edit: Yup, I'm giving up. I think I'd still try to get S rank on rest of the game if it weren't for the platforming in the latter half of the game. It just becomes too frustrating.
