XerObot: Hmm... I'm not sure about the breeze thing. I don't know if it's actually long enough for any hair bouncing to be noticeable. I might try to see if I can or cannot actually do that later though.
And as for the idea of making her blink, I actually already did something rather interesting: I've programmed this loop in the Acrec object that, every 5 to 10 seconds, places this "eyelid" entity just over the sprite to give the illusion that Acrec is blinking. There's also a thing that makes it so that whenever the player starts walking, it randomizes which leg she puts forward first.
UPDATE: Wait, when you're talking about hair, which bit of it are you talking about? The one just above her face, or the one hanging out the back of her headscarf?
