Please add Apple Pen support

I love sudoku, and not evil sudoku is perfect, except I cant’t write with my pen. I’d be willing to pay the one time fee for everything in the app if I can write my numbers in,,,

App lives up to its name

(Tldr: if you just want to play Sudoku, look no further in the App Store. This app is perfect.)

I’ve been really impressed by this app and it’s author. The app has continued to be refined with each released update. The app has only gotten more user-friendly and even less evil (if possible). There’s no ads, there’s no BS, there’s no jankiness. As silly as it sounds, it’s honestly a refreshing experience seeing an app have this progression, even if it is just a silly Sudoku app.
