Seems i'mma have to step in...
(This review is a collaboration for all three of your 358/2 Days episodes)
Before I begin - I for one love all of your parodies, as well as the unique touch you put on all of your works. I've seen how much your animations have improved over time, and have become a giant fan of yours.
First off, I like your pre-loaders. XD I can see how some people would have a problem with it, but the preloader for your 2nd one of this series was by far the greatest XD It definantly made me laugh and not even notice the load time (Although it was fast anyway).
I've noticed your graphics have dramatically improved. Your movements look more smooth (Sora's running in Episode 3 was really nice, and the first episode all around had smooth movements) Your animation skills really stood out to me during Holloween Town's mission with Jack debating what to do and Roxas in the background fighting. I was thoroughly impressed. (The Preloader for episode 2 was amazingly smooth and well animated!)
Oh! Your shading has also done well, as well as your backgrounds! In the beginning (Around your "Sonic Movie Madness" days), sometimes the background would look rushed, or bland, and the shadings wouldn't match with some of the lighting, but that didn't seem like a problem now. In fact, you've impressed me with how well you utilize shadings and details (Again, especially in the first 358/2 Days episode) to make a really visually appealing scenery (Really impressed with your Twilight Town and Organization XIII Building).
Your music choices also did well to add Drama, or humor to your scenes. Although some scenes I thought were awkward with the music choice, I still saw as to why it was placed, giving an overall better or more distinct feel.
I also liked the references to the previous "kingdumb hearts" parodies. They added a tasteful reminder to the hilarity to some of the situations that Kingdom Hearts encountered through the games. I also found the "Forsee" instances with Mickey's assistance to Sora and the gang in the second game from what was said in Kingdom Hearts 358/2 Days rather funny- Not to mention the hilarity of Xemnas' "role".
My main complaint is you still haven't got smooth Closed Captions. They are often shortened, or incorrect. There also isn't a Character name which makes it tough to read and see who spoke (For my loud house). However, it isn't that great-a-deal as I could just watch it again later, and it was also done on the third one where each line is one character, so it's easier to keep up. The lip synching was also greatly improved on the third one as well. Some points you could literally read their lips (Which I might add is an amazing improvement to your old style of making characters open and close their mouth to speaking).
Overall I see how amazing your animations have become. You're really talented and it's apparent how much work is put into your Flash projects. I have to give this and the rest (As I already have) a 10/10 and a 5/5 Amazing work! I really look forward to the finale.
Apologies if the Review is tough to read XD Had to put down my thoughts before I forgot again. > <
