Hero mode completed and...it was a bit underwhelming to be honest. Was expecting a larger difference in the ending screen or some bonus goodie. All in all, it's just the same thing as the main game with 4x damage from enemies, that's all.
Breezed through it in less than 8 hours, collecting everything except the 50 streetpass medals. Once you know the order of dungeons to tackle to maximize your Master Sword, Maimai collection and Armor, the game gets too easy even on Hero mode.
