The choice of music and pacing of the dialogue worked very well together. Great atmosphere and intensity, especially nearing the end!
I couldn't quite understand the story. SPOILERS AHEAD: I saw a dead body next to the sword at the end. Maybe that was a previous hero who unsuccessfully challenged the narrator, but could it have been someone/something else? I dunno.
It's been mentioned but yeah the platforming was a bit janky, namely colliding with edges and jumping on slopes.
