I have updated the link to include a block/parry mechanic.
It only works on the rust colored enemy that lunges at you.
Press C to parry, if you successfully block it you can quickly press X to riposte with a 2x strength attack.
(only while standing until I test to see if this is where I want to go with it, if I'm happy with it, I'll implement it for crouching as well)
I'm wanting it to block certain melee attacks and projectiles like in Zelda 2, but more timing based as apposed to the more passive shield. The riposte also gives a bit of a reward for pulling it off as well, though it might be nerfing that enemy a bit...
Not sure if the timing is quite where I want it, but I think I like it so far, and it just begs for an enemy that can parry and riposte back at you.
