Square Enix has released Kingdom Hearts Unchained X[chi] on iOS and Android in Japan. But, don't worry, it will be heading west at a later date.

This mobile version of the game is based on the Japan-only browser game. It's a side-scrolling MMORPG in which you play as a Keyblade wielder during the Great Keyblade War.

It has over 300 short stages to beat that have you flicking the screen to attack enemies. There are also, of course, boss battles to take on and plenty of Disney characters to meet.

As you progress, you unlock more characters, some of which are playable while others will act as support during battles.

You can download the Japanese version of Kingdom Hearts Unchained X[chi] for free on the App Store and Google Play right now.
