You should make the game anyway just without charging anything for it. Of course donations will be given by fans regardless.

More seriously, you could think about creating a test level or demo to get some media attention and the ball rolling with Disney.

For support, I would buy this game 10 times : Android, iOS, Steam, Xbox, Playstation, Wii, Vita, Ubuntu, Windows Store, Ouya.

But I would only play it with a mouse, voodoo2, and adlib sound card.
