At first i wanted to use numpad keys, but the order on pc numpad is totally different than on phone keyboard, so i decided to use letters. I should've added an option to switch key settings, but i didn't think of it at that time.
Like I said, it's not too much of a problem. It's worse when the game is action oriented and depends on quick inputs. Just something to keep in mind for the future.
I had to learn this by not catering to it and getting reviews from frustrated frenchmen myself. :D
