All four of the game's areas are shown, along with a bunch of the game's tools and items. You can also hear what the game's music and sound effects sound like.
The game will be released on the Wii Shop soon - We predict Europe gets it this month due to Nintendo of Europe saying it would be released within WiiWare's "launch window", but the US has no firm date or even announcement yet.
The sooner it's released, the better!
