Have a look at the screenshots on our Madstone game page or watch the video below.
Here is a bit of blurb about the game from the developers which explains what to expect in more detail:
RiverMan Media is thrilled to announce the development of our first WiiWare project, MadStone. MadStone is the most intense, dynamic, and relentless puzzle game ever created.
MadStone is a dynamic, tension-filled puzzle game with an earth-shaking twist! In a landscape filled with crumbling ruins, you use the Wii Remote to smash through rubble and release the power of ancient magical spirits. As you gain in power, you can literally shake the earth itself, unleashing vast amounts of energy and leaving your opponent in ruins.
In MadStone, you clear through towers of stone in order to collect the magical elements, called SkySigns, that are trapped within. The goal is to get your SkySigns (moons in the screenshots) to the bottom of the screen, where they are collected in your mana pool. Collect enough, and you can execute a super move that causes an avalanche of destruction!
