Due to the rain coming down and blurring the screen, it is very difficult to tell that the selected difficulty has a slightly lighter border.
If the border is the difficulty selection options... my I suggest switching the selected and non-selected borders?
Have the selected one bright and the non-selected dull.
This would be more intuitive and make the current difficulty stand out more.
Also, if you switch them, could you dull the non-selected borders just a little more to add contrast?
