The La-Mulana remake will arrive on WiiWare soon (September 20th) for 1000 Wii Points ($10) in America, Europe, and Australia! In honor of this joyous occasion, Nigoro has concocted a "beginners guide" video and shared it with the world. It goes over mechanics as basic as entering tents, all the way up to inventory management, what items you should be buying early in the game, and what you should be doing in the ruins.
I have to warn you right now though: it's best if you go into La-Mulana completely blind. As in, don't watch any beginner's guides posted here (cough cough) unless you really, really want to. The game is much, much, more fun if you have no idea what to expect, and figure it all out on your own.
