I've noticed whenever I try to parry a the red indicator gest brighter and "blinks". Whenever I see that I attempt to parry but I realize if I do it right away the block will sometimes not work. I'm not sure if this is a bug or if this is suppose to happen. I know I could wait a extra second but when I'm in mid-fight its hard to remember those things as adrenaline is high and you're thinking about your next attack.

I'd also like to suggest being able to change the color of the indicator. Like setting it to a certain color like yellow, or maybe setting the color to change when the indicator gets larger.
