What's the difference between the All Bosses category on the the All Chapters leaderboard and the All Shadow Crystals category on the category extension leaderboard? I cant really see a difference between the two. in All Bosses category, you have to defeat all bosses, including jevil and spamton, and beat the game. In All Shadow Crystals, you need to defeat jevil and spamton and beat the game. But there are no other bosses besides those two and the required bosses. What's the difference between them?

In All Shadow Crystals instead of doing Main Route in Chapter 2 you do Snowgrave. Beating Spamton in Snowgrave gives you both the Shadow Crystal and the PuppetScarf.

Normal AB requires not only jevil and sneo but also king, queen, and giga queen
