One of the newer WiiWare titles confirmed by Nintendo recently is a neat action/puzzler currently titled Night Game.
From the developer of the WiiWare Cave Story remake, Nicalis, Night Game has been described as a "part action game and part puzzler" where players use physics to move about a glowing sphere through different atmospheric locations. The team hope to give WiiWare a unique art and music experience, with it already up for an award at the 2009 Independent Games Festival.
