I cannot tell if this is a powerup or feature, though that seems unlikely since this does not occur when moving vertically. When accelerating with the ship pointed left, right, or diagonally, it randomly speeds up to a very fast speed, then quickly decelerates to it's original speed (speed cap?). I'm going to set up a dev environment and see if I can't find what's causing this.
