Pretty good. Personally I think the part that could use an improvement is the parry. This might just be personal preference, but I feel like parries in games should be harder to pull off but more rewarding. Something like shorten the parry window but have it do some damage to the enemy. It also felt weird having the boss have an attack you couldn't parry, but could block. I assume, though, that further in development there will be other attacks that work the opposite way.
Even without any of that, it is looking like a pretty solid game, especially for how early in development it is.
