First things first, excellent concept, and a very good start - What kind of game-play are you envisioning? It sound like it's very similar to Kingdom Hearts (also with the character name Sora (the main character in KH)), but from what you said, I can picture more of a third person wasd system.
Keep the ideas flowing! Do you have a blog/site/display space for any of this, or is it all internal?
Replied to what you said in my post. Also no, I don’t have a blog or site or anything like that. Should I create one? Since this is new, I hadn’t really thought about going that far.
Still in the middle of having a look at the game design though, post that up later.
Just added the Game Design.
