I liked the pixelated, vintage, old video game theme and sound effects.
It needs better animation or more of it.
The lipsync was fine.
I'd do without the "pokemon" attack option box, and actually animate the fight scenes.
I know that you were trying to make this feel more like an old video game, but it's like you took the easy way out with the "attack option box".
The story was horribly depressing (especially at the end), with no point or hope for any of the main characters at any point during the story.
