For a demo, and possibly a useless one at that, I would have to say that this program is positively inspiring!
I'm not a fan of Pheonix Wright, since I had the time to follow up on only the first game in the series. Regardless, though it's just characters talking and moving their mouths, the graphics are beautiful, and hint at a VERY IMPRESSIVE Pheonix Wright game in the works.
Animation flows smoothly, I suppose. The Pheonix Wright character was drawn the best, in my opinion, but the others weren't bad. It ran pretty fast and could have controlled better, but I'm very optimistic about this author's plans in the future.
Of course, those currently who do not have the luxury of being able to download this at the time can watch this impressive video demonstrating the game, which he has linked in his description:
