A playable demo of Sonic Lost World is now available on the Japanese eShop and for some reason the Japanese demo includes English audio. Perhaps the retail version of the game will include dual audio? Anyways, Nintendo World Report was kind enough to record some HD game-play footage of both the Nintendo 3DS and Wii U versions of the demo and upload it for Sonic fans the world over to see. Scroll down to check it out.
Sonic Lost World will be available on October 29th.
