i think the "thing" that people are seeing when they think it looks bad/flashy is because the disparity between the animation of the sprites and the actual framerate of the game.
when characters move around, it could look as if the sprites are sliding across the play field or maybe they look disconnected from the character's positional movement vs its animation movement.
i changed the framerate of the gif above to reduce the disparity and you'll see sort of better overall cohesion. but the problem with doing this is that then game then has to run at a lower framerate.
WOW! This looks pretty good to me.
