What's with the dialogue?
First off, I want to say, the action is freaking killer. It's beautiful, wonderful, I must congratulate you on using a limited sprite sheet to its best advantage.
But what kills it for me is the dialogue. Seriously, I was saying lines three or four lines in advance. It's HACK dialogue man, not much else to say.
And the PLOT... It's like you painted yourself into a corner after Episode 2 and you've been paying for it ever since, man.
The concept itself is very nice- At least, as far as I can tell. But this isn't X's story, and it's certainly not Alia's. The story is only really beginning right at the end of this episode, and from the beginning of the last.
I have a funny feeling- and tell me if I'm wrong- that this is the Lights' story. These old, forgotten things, left to lie in wait and hope against hope. It's shapting up to be interesting.
As it is, though, the dialogue had me laughing out loud, which I take is NOT your intent. Work on it. Please.
