If someone just simply pulled Richter's leg to the left of the screen inward, and placed it on the slope rather than inside of it, it'd be pretty much fixed.
EDIT: I'm gonna suggest this, since it popped into my head. May as well do it now, since I'll forget later, and if you do decide to implement it, it won't be til MUCH later...
Remember in the Castle Keep, the stairs are destroyed when playing as Alucard? I was thinking, to make the area more interesting, what if after walking up a set distance on the stairs, they collapse? Similar to the bridge in the Clock Tower.
