In particular, it's the high pitched click whenever you move over a square or when text displays during the tutorials. I'm wearing headphones and my ears are in pain after playing the first 30 minutes, and I almost never get earaches from anything, even from listening to loud music. My only option is to play with the sound at the lowest setting, and even then it still kind of hurts.

I hope the high frequency sound can get filtered in an update, or maybe an option for a softer sound effect could be added to the sound menu in case some people still want the original if they're already used to it.
