This game looks and performs phenomenally. The overall presentation, from the intro comic to the way each new run starts and the level transitions, is masterfully done. The addition of different types of enemies and level obstacles creates a steady difficulty scaling. The sound design of the bullet whizzing past as it moves faster added a lot to the enjoyment of moving it around the screen. I could see this game having a different game mode where instead of playing out like a marathon, you'd have time-attack or precision levels.
