Kingdom Hearts Re:Coded is the DS remake of the JP-Only title made for cell phones.
The story takes place after the events of Kingdom Hearts II, where Jiminy Cricket and King Mickey are archiving the Jiminy Memo of Sora's adventures. While leafing through the journals, they find a mysterious message...
"Their hurting will be mended when you return to end it."
To make heads or tails of the message, they enter the journals into a database, only for it to become corrupted, with some of the information rendered unreadable. They then task the Data Sora to go through the digital journals, removing bugs and investigating the the meaning behind the mysterious message.
It looks like it will use a combat system very similar to Birth by Sleep, using normal attacks and Dodge Rolls while magic and special abilities like Strike Raid are used with the cool-down system. Although the gameplay seems to take several different turns, since just from that video we see the normal KH gameplay, a turn-based encounter system, some Mario-style platforming, stealth, and some rail shooting-esque events.
