I hope last boss will be locked until you expanded most of the worlds and collected almost every pagie, i loved the final grunty painting where you had to fill every space with jiggies so the game itself forced you to go backtracking and find every single jiggie, that was hard the first time,
i hope YL force you into some kind of this at a certain moment, because once you defeat the last boss there is something done and the game feels strange after that, like if its over,
Playtonic team said you can play the game your own personal way/style, even beat every world after world without expanding but reaching the final Capital B without expanding every world would just feel wrong,
Maybe something like: every boss battle holds a key, you can only acces to boss expanding the level, to acces to final boss you have to collect every key (like in diddy kong racing with amulets)
I really hope there is a big reward for every single pagie collected, maybe the second part of boss fight or a secret level (also like in diddy kong racing, the final space races)
What do you think??
