The game was very addictive and fun to master. By the end of playing I found myself parrying over and over to lay the smack down and that was a good feeling. The fact that every single attack can be parried was awesome too.
However, I think the parry may also be the game's biggest weakness. The parry timing is very generous and healing after every successful parry makes the dominant strategy to stand still, wait for the boss to attack, and then parry and mash attack. It's fun to master that, but can feel a little one note and repetitive.
I still had a good time though, great job with this!
