Hard as nails, but I like it! A parry timer would be nice, audio and visual queue or something. Love the art and animations!
You already have it. Whenever you parry, you lose your mask, and you get it back when the parry cooldown is over, along with a sound similar to a sword being put in a metallic sheath.
Additional your Scythe will stop glowing while your cooldown is running
Oh, didn't notice that. That's cool.
