* Before the map overhaul, there's the appropriately named "Star Gate" that has keyhole which, once opened by collecting enough stars, you can use it to travel to the next world. Except for collecting stars instead of using keys (which ironically have other functions in this game) to unlock the keyhole and travel to the next world, doesn't it remind you of [[VideoGame/KingdomHeartsII certain video game]]?
