- When you attack anything successfully, the bar to the left of Sora's face builds up.
- Each time the bar fills up a complete level, certain buffs seem to activate automatically.
- Lvl1 = Medic, Lvl2 = Spirit Attack, Lvl3 = Attack Boost.
- When Sora levels up, it says "Level Up! Gained Level Up Chip!" which indicates that the panel system from 358 is likely presented as data chips instead. Definitely not a normal KH level up system.
- Aside from leveling up, there's another pop up that says "Power Up! Kingdom Chain 2.0 Clock Ability Unlocked!" which could indicate that aside from leveling Sora, the keyblades could also level up and unlock more stuff?
- One of the item drops Sora gets is "Fire Blast" which definitely indicates that commands are equipped items, just like they are in BbS. Neat!
