+When they spoke to Tabata before making the transmitted version of coded, they began talking about how they wanted to make a Kingdom Hearts theme park, and the concept arose of an 'attraction RPG' in which the play varied for each world. It is for this that the battles were extended and diverging.
In this title there are several power ups, which gives a fresh feeling while playing.
+The main premise of this title centres around things that were introduced in KH (first game). From within that, they chose to put in each different battle gamplay system, and make it rich in variety.
There are also worlds that are difficult technically to complete.
The truth is, they wanted to add the gummi ship. They thought of adding it for the remake, but, time-wise there was enough strain as it was, so they didn't bring it up.
+Olympus Coliseum appeared in full so that the plot setup came to life properly in the game, and on top of that, to make the components that were put in fit nicely.
+There are more than 800 kinds of avatar parts. All the ones that were in KHMobile were re-pixelated and edited.
If you use Mingle Mode you can receive scratch cards and system area parts from your partners, and you can also get some kind of part from the scratch card. Also, if you clear the gameplay area floor trials, the arrangement is such that you can receive one of the parts that your partner is wearing.
The contents of the scratch card also change depending on how far your partner has gotten. It might be more profitable to connect with people who have played as much as possible.
The parts you have from the beginning are also different from cartridge to cartridge. Also, because you can receive scratch cards and floors from other cartridges and from public wireless LAN waves, so they want you to try using Mingle Mode actively in many different places.
+The avatar gameplay area is 100 floors max, but:
Nomura: "I suggested that of course we absolutely had to have 100 levels for players to savour a real feeling of achievement."
Test playing took 2~3 days, and of course the game was corrected over the things that came to light. They think that an experienced player could complete the game in a few hours.
It may be easy to collect 100 levels, but of course if you don't clear them you can't receive parts or SP, so they want you by all means to try and clear them.
You receive a title for clearing 10 levels on avatar gameplay area. Raise your title, and the trials you can send partners also rise.
