Sudoku Dark Mode

I am a sucker for Sudoku's daily challenges!

Every day before I go to bed, I check the app for the new daily challenge. However, Sudoku's light mode strains my eyes, especially when I'm trying to relax in a dimly lit room. So let's design a dark mode for the app, and hope they consider adding this feature soon!
