Crown Stickers are often placed in stages so players can see them, but have to take another path or route to get them. Expect platforming-esque challenges from this new system. If you’re up for a challenge you’ll get some kind of reward. Placing Crown Stickers in an album will unlock prizes, but Square Enix wouldn’t say what they are.
The North American version also has a new boss, a secret boss who will be the hardest fight in Kingdom Hearts: Birth by Sleep.
