yeah what does changing the sleuth theme even do. I have the option to choose from two. Shady character or classic. Which in your opinion is better and why?
A theme is just a background, like a desktop background. You can change the "look" of your game by changing your theme. You can unlock themes as rewards, or you can buy them around town.
Themes do not do anything except change the look of the background. Go ahead and change them and see which you like better.. (hint: look in the upper left corner for the different pictures as you change themes)
