I think it's better than KH1? my only problem is again the combat system, I don't really like the command deck, but DDD is probably the best handheld KH game by far.
DDD is kinda weird to be honest, but hey, they got TWEWY characters, which is neat.
The worlds are... Surprisingly large, considering it's a 3DS game, I guess they were cool, but flowmotion is broken, I don't know if they intended it to be that way, so I guess that's a good point?
In the end, it's fine.
