thanks. is it because the font is too large?
It seems to be set up for gamepad control, where you just push one of the sticks side to side. It's a bit awkward trying to use a mouse, sometimes things on screen that appear to be buttons for the mouse are not, other times they are buttons

Not a huge issue though (although some peole would say it is), you can get use to the clunkiness quickly ... and I'm sure mods will be out soon for a UI that works well with the PC.
As far as the mouse goes, I just maxed out the "look speed" (I think that was the name, it's not "mouse sensitivity" like you would expect), and it felt ok to me :shrug:
