Yes, the game has somewhat skeuomorph graphics but don't have skeuomorph behavior. If the letters would look more like buttons then i think you wouldn't try to drag it because you don't drag a button in real life (when trying to use it intuitively). Edit: If they would look like keyboard keys then that would also suggest that you can use the keyboard too as mentioned in another comment.
