Super cool, I was initially drawn in by the art style, and the character design! Definitely thought "Woah, I'm pretty interested in what this is".
I like the approach of all the NPC's trying to seem non-threatening before they start rushing you down and stabbing you, definitely trust no one! And then, they start running away, and I feel like I'm the bad guy now. The atmosphere is very mysterious as well, I like it. Makes me want to know more about what the story really is.
It does get a little monotonous after sometime though, since the loop is simply "go up, hunt this person down before they kill you, heal up, repeat". I would like some freshness to spice things up, maybe some NPC's that really are friendly before you stab them because you don't trust them.
It was fun to play, good work!
