Two things struck out at me in this game that should be upgraded in the next zelda game for sure.
what it needs: voice-over work
what it has: endless amounts of mostly useless text
what it needs: Real free motion sword fighting
what it has: Every gesture has a predesignated effect and animation. Every time you try and bring your sword to a horizontal position (in order to do a horizontal slash) you might accidentally do a cross-diagonal slash, and so far and so forth. This is problematic if an enemy is blocking for that very position.
