From a technical standpoint, this game deserves a perfect 10. It is no Power Strike II, but it still is one of the most visually stunning games you can get for the SMS. So, it's really a shame that with only a bit of adjusting it would have been perfect in every possible way. The game is too short to require a password system, but I really feel some extra continues wouldn't have hurt. As it is, it can get really frustrating, especially in the later levels. Highly recommended for those who want a challenge, but everyone should give it a look, because it's a Taito timeless classic very fun to play.
