It's unfortunate because Uzumaki Chronicles 2 has a nice little RPG system going for it. Fitting in skill chips like a puzzle to enhance abilities is cool, and leveling up the numerous characters is almost enough to justify the grind. That is, if it weren't for the orb collecting. Fallen enemies drop Virtue orbs, a la Kingdom Hearts, which you'll collect as XP to level up. But when you're not getting killed trying to get to them, they fall over ledges, scatter out of bounds, or in some cases, you'll accidentally hit an unmarked exit and leave them behind.
