This is really excellent! I love the slow paced movement and atmosphere. Got Bloodborne and Thief vibes from the environment. It's brutally difficult too, but feels like I could get better with practicing. Does the violin stinger hit right when I should parry? May be worth having that audio cue a fraction before so that players have a little extra time to react (unless it's already before and my reaction times are just terrible these days XD ).
Also brilliant work on the music. The dark undulating strings really sell the tension. The procedural maps don't feel too rigid and will add a lot of replayability.
I can't praise this enough. Added to steam wishlist and I will be keeping a close eye on this one. Great work!
