You play three characters and can swap between them via the inventory box. However, in a few places only one character at a time can be activated. Each character can carry up to four items. All coins and knowledge are shared, but inventory items aren't. There are a few places where you can die, but these can easily be avoided. For reasons you'll have to find out for yourself, consider Daisy the 'leader'.
