Pagie Spectrum. Colour-coding pagies to show which world's skills you'll need to grab them. Makes it easier for completionists to not get bogged down fishing for Pagies they can't collect.
Green Pagies: By the time you've filled out the Jungle World moveset, you can get to these Pagies.
Blue Pagies: The Pagies representing the Ice World. If you see these pagies in the Jungle world, then you know it needs Ice World moves to reach it. At least as intended.
And so on through each colour. With that said, there's... quite vaguely "More than five" worlds(you cheeky developers, we know that means six
), but 7 colours of the rainbow. I was thinking the remaining space could be filled with Transformation Pagies - so I don't spend twenty minutes trying to reach a pagie only... iunno, Yooka can reach. Or, you could use White/Black/Brown pagies to fill out the roster, if it really IS more than 5 worlds.
