4.6 Item acquisition total (+Value)
The item acquisition total, or "+Value", is the core scoring system in the game. When you reach 1000 on the item counter in normal mode, or when you enter Power-up mode, every item absorbed adds to your +Value, which acts as a point bonus added to every item you absorb. It is displayed next to your character as it increases. The maximum +Value is +10,000, which is colored a bright orange. When you reach this, you enter "Fever mode".
I am playing X360 mode and i don't understand how you enter fever mode. I don't see the counter that you describe unless this is a feature of a different mode and i tried them all. Can someone explain this aspect of the game a little better for me? I apologize if i overlooked the obvious, Thanks
