First play through I didn't notice any change after each count down (I must have gotten lucky I didn't get any super noticeable event). 2nd playthrough I noticed the text and icons telling me what was next. I liked the vector lines showing the path of the asteroids, not something I've seen before on an asteroids game. A very hard game but fitting for the arcade style. Not sure what my high score was, but it was likely my very first playthrough.
