I find it very very difficult to believe given what we were shown from that game.
The current version of the article cut the identity of the dev they spoke with, who I
did look into at the time, finding nothing definitive from his social pages, which I can't even find now.
Furthermore, KH13 also reported on GFL Animation Studios providing the art for the game.
At the time, their official site (a Blogger page) had a section for their work at Disney Interactive (not just Kingdom Hearts). Today, there is no mention on that site of Disney Interactive nor any of those projects. Their pages for Kingdom Hearts, "Epic Disney," and "Thor" are gone. The "Star Wars Cartoon Concept" panel is now renamed "Star Wars Inspired Art 1" and "Star Wars Death Star" to "Star Wars Inspired Art 2."
And these changes were already made by the next Wayback capture in May, only a few months after the article published.
(I've just sent an email to GFL hoping to get an explanation. Fingers crossed.)
Maybe Wideload was working on something.
But I simply cannot bring myself to believe it. It just has that stink to it.
