I don't know if its just my end but I found the game had a good 1/2 second of input delay on every action. This made it very difficult to get the right parry window.
Unfortunatly I couldn't get past even the first boss due to this latency, so I'll judge based on what I've seen so far.
The art is really nice and fitting for the game, and the boss seemed to have a decent amount of telegraphing. Honestly if the game were working smoothly I could see myself enjoying this one.
So it really is a shame.
