Beat it for the second time last night as I lost my save after I had problems with a faulty Wii. First time I beat is was just over 40 hours. Last night was just over 30, and I had more items (including all hearts). Just gonna go back to find poes and bugs!
40 hours for the main storyline,16 hearts,2 bottles,only need one more upgrade(forget what it is lol),completed cave of ordeals once. Other things as well but I cant remember.
