The central gameplay can be very engaging, once the player figures out that they can dodge in midair and that chasing after a lost sword can let them play aggressively without risking health. The animation and audio design of the lady in the temple is fantastic. I wasn't able to figure out any means of progression past that point - finding various weapons around the world added them to the arsenal of enemies, but I was unable to find a way to clear it to the lady's satisfaction. The area to the left was interesting to traverse but only seemed to have a loop back to the starting area. I enjoyed my time with this unfinished artwork. It's bittersweet.
