It would be nice if besides being able to adjust brightness we could adjust blackness as well, kind of like brightness but adds a darker shading such as a deeper black. I've noticed on different computers that how black a computers screen displays things differs quite a bit between systems and a simple brighting bar doesn't do anything in terms of the blackness/dark cast the computer has. Anyway it just seems another darkness bar would be nice.
Also on different screens the life ball and cards differ a lot in size based upon the screen size option. It would be very appreciated if you had an option to increase the card and health ball and other such icons. Barely changing the screen size can half the size of the health balls. I'm playing at less than full screen so that I can have a health ball that is twice the size it would be at the full screen resolution.
