In both gamemodes, the circle that appears when you are mining is too big. It used to be fine, and could be adjusted with the dpad, but know its about 2.5 inch diameter on the ipad, and its just distracting - also it cant be adjusted this time. It was supposed to have been fixed for 0.7.4 having appeared first in 0.7.3. Now we're on 0.7.5, it must have been missed.
