One important recommendation - the special attack should be able to damage traps, at least the ones in front of you. The silver bullet boss is incredible frustrating to deal with when dodging would leave me out of stamina but parrying would actively get me caught in traps and open for a three-hit combo.
The ability to bind controls would also be nice. I almost never use the special attack but frequently like to parry, so switching the two keys would have been a nice option.
