I love Sekiro! I'm very surprised by the quality of the bosses. Keep working on it and you'll end up with a great product.
I did find that the bosses got some tracking issues. Some of their attacks are not great as you can just effortlessly move out of the way.
The players kick also seems very strong and was very noticeable even during the initial tutorial. I decided to play honest for most of the game but at the very end I started to spam kick more and it made the game trivial.
