Congratulations!
I've been watching your series since the episode 0. It's clear the evolution your going as a story-teller as well as a flash animator. It's unfortunate that one must be ready to read all those extras to get deep into the settting of this reality (which by then it is curious to even call them "extras, but that's off-topic). I am a fan of deep tangled plots and I've worked on several RPG plots, as well as story-telling. I've got to say I can see potential in your story-telling abilities, but still a lack of efficiently profit from that talent. The fights keep getting better. I like how you slowed the pace of the fight just a little bit, comparing to episode 2, where I had to watch the fight a couple of times to figure the moves. This one is a well-thought coreography (the must was the falling sequence: "Open wide!" That was just brilliant). The fight was really good. About being short, well I don't know. If it getts long it'll feel repetitive and will lose it's beauty. I think you measured well how long you could extend the fight with the moves you had available for the characters The artist CE-Rap did a great job, I loved the Panaptichron setting, it was mystic and unique, really got that "nowhere palace" thing to it.
I won't suggest anything, has what you should or not do with the flash, I'd rather slap that sentence from Stryker: ..."Do what you gotta do." I just wonder, when you want to do a finishing signature move of a character (like the gambit throwing cards), you normally black the screen a bit and have some specific special effects. What about having an image of the character doing the move, cutting half of the screen (or a desired space). Why? Because when the character is going for the move the rest of the screen is just frozen... looks empty. It could give also a good challenge to CE-Rap making him do some art of mid-fight images.
As for the stars, I'll give you both a 7 (while my heart gives you a 10). But this is not a normal seven. It's a seven that knows you going to get better, a seven that understands the levels you both can still achieve. It's a seven that hunger for more! Why, it's your lucky number 7.
I wish you both the best. And good luck for your future projects.
Sorry for the long review, I kinda have a thing for writing.
