Puzzle mode is entirely separate from survival mode on Magical drop 2, and can only be accessed if you set your Zone settings in the Dip Switches to Japan. There are three games under Puzzle Mode, and max score possible is less than 100k.(posted 9195 days ago)Heh, come join the Magical Drop fray if you dare, Steve. I certainly no longer hold the crown at MARP.
Selecting secret characters has something to do with the time remaining in the select screen, if I recall. There's one or two MD3 faqs out there, but they're pretty basic. Someone had a webpage devoted to the game with all the different character attacks and patterns, but damned if I can find it now...
