Looks promissing
Looks nice and clean, no real sloppy parts in it. Only visual part that i didn't like was when you zoomed in on the sprites, they looked kinda blurry. I think it would be better i you'd leave the sprites in solid pixels instead of letting them get smoothed.
And i don't wanna be a prick, but i think the music choice was rubbish. The first and the last songs were pretty good as they didn't sound too bad and fitted in the situation pretty well, but the second and third sounded absolutely horrible and they didn't fit the scene verry well.
I also didn't get much of the story. I'll let that slip because you already told us so and i'll expect it to be clearer the next time, But...(yes there's a but) i think you should find a way too cut down on the filesize so you can put more into one episode, because this one didn't really show that much, it did make me curious for the next one though. I suggest doing something about the audio since that's often the reason for a big filesize (i know because i had that problem myself :p).
Anyways, looking forward to understanding a bit more of the story and watching the fighting scene on the next episode.
