For some reason the uploader set all audio options to 0%. Go to game options to fix it
You really aren't missing much of anything. There's no game here, it's just a scene viewer where you walk around and see a scene. No corruption, and the clothing/character customization is all meaningless, you can only see changes in the menu and on pixel art. NPCs don't react to clothing changes or nudity or anything for that matter.
NPCs might as well just say "Welcome to Corneria!" and "I like swords." That's about how deep the game is.
Main character doesn't even care about sex. First scene I saw was vaginal sex and the MC was like "Oh. Okay, whatever"
