This is the high-speed version of Sekiro I’ve always dreamed of, and I absolutely love games where the protagonist has immense mobility and movement skills. The fight against Nia is my favorite—her moves and animations are incredibly cool. I initially thought the terrain would make this battle frustrating, but dashing between pillars and corridors with real-time environmental destruction turned out to be absolutely awesome. That said, there are a few minor issues. The grab attack after Nia’s yellow flash has some hitbox problems—sometimes she misses me even when I’m right in front of her. Her rising kick into the aerial kick comes out too quickly, making it very hard to react to. Also, when she uses a downward kick to block my shurikens, I take damage inexplicably even when I’m far out of her range and her kick clearly doesn’t connect.
Moreover, Louise’s AI behaves oddly at times. Sometimes she just stands still in front of me for a moment, and other times she attacks the air from a distance. Her close-range spear thrust also often misses.
Still, these are two excellent boss fights. If the transitions between animations were smoother, it would be even more amazing.

Thanks for playing. Sorry for the late reply, this was stuck in approval hell and I didn't see it until now. (and SOMEHOW bots posting phishing links don't get quarantined)

Actually, her grab attack is meant to be easy to dodge, since it's quite deadly if you get hit by it (although it doesn't directly kill you). In the setting, this technique is supposed to be really hard to use effectively, which is why you need to practically be standing still to get hit by it. The somersault kick is a little fast, and I'm planning on adjusting the timing next update. 

For the shuriken blocking, just like how you can parry some projectiles, enemies can also parry yours by just attacking. I think the speed and effects on this are set too high that it immediately travels across the map to hit you before you can see it, so I'll look into fixing that next. 

Louise's AI is frankly quite a mess at this point and I plan to overhaul it at some point. 

There's also been some other updates to the game since this post was made, so please do try the new changes.
