I liked the game and I had fun with the retro style hidden paths and I didn't really have a problem with the mixed graphics, but for me lots of the weapons either didn't work or were weaker than the rusty sword. So the Black Talon, Executioner, Prism Staff and Chaos Trigger didn't give me any attack skills and the light spear, and iron serpent were both weaker in attack than the rusty sword.
So I finished the game with the rusty sword, patchwork coat and the great root ring.
Other than that I enjoyed the story and the mood, as well as both endings. Well done.
