I must say I absolutelu hated the inverted camera controls. For me the game is unplayable. I think, every game design decision should have a purpose. And I don't think inverted camera adds anything of value. I also couldn't interact with letters half the time. First time I managed to take one letter and put it in place of another, but couldn't do anything else. Another time I could only take one letter. And I didn't want to keep trying because of cluncy camera, that irritated me.
