I am a little disappointed that the movement is locked to 8 directions like the original. Of all the aspects to bring across, this one poses no obvious advantage to me. I find such movement tiresome in modern games and can't quite wrap my head around the thought process in keeping it.
Perhaps there's some section of the game that would suffer from the more widely used full analogue controls I was expecting. In such instance, however, I would have respected the game much more for having fixed such sections, rather than locking the full game into a control system so outdated on a console with joysticks.
I'm hoping they give the option to switch between locked directional movement and full analogue. A little like Pokemon X and Y did rather unceremoniously with the ability to equip roller skates that opened up all directions.
