There is now a new area on the official La-Mulana WiiWare site created to cater to Western audiences, hosting all of the media already shown to the public so far.

You'll find little that you haven't seen on the Japanese version of the site, but all that is set to change when they reveal more juicy information about the game (e.g. Boss Rush DLC, new Hell Temple) in the coming weeks leading up to its release date of Nov. 2009. (source)
