Pandora's Tower is a really good game, all you people with a sealed copy should play it. The combat is fun and the boss fights are great. Of course when you get to the Light/Dark tower, I'd strongly recommend using a guide so you can beat these towers as quickly as possible since Xseed created a nasty glitch in the North American version that causes the game to freeze randomly when you try to enter those 2 towers. I ended up having to reset my Wii 10 different times in order to complete those towers since it seemed to freeze ever other time I came back then tried to enter again.
Oh and make sure you get all the exclusive items in the Light/Dark tower as well since the glitch happens 100% of the time during new game +. So if you didn't get everything in those 2 towers your first playthrough, it's impossible in your second because can't enter the towers on the second playthrough thanks to the glitch.
