We have just released a new trailer of Zelda: Mystery of Solarus DX. It contains various elements of the beginning of the game, including small details (such as walking on stairs and tapping against a wall with the sword), the fight with the boss of the first dungeon, and a sequence of the second dungeon (which is not present in the demo version). The music of this trailer is an original creation of our team!
I hope you will enjoy it!
