Very solid shooter. Great variety of stages and locales with unique enemies depending on the environment, the shooting is very satisfying with lots of explosions and destruction, 8 different planes to choose from (although only 2 are viable imo), bosses are well done with transformations and weakpoints and a good fit to the theme of the level, instead of just being the standard generic spaceship or monster. The second loop is much more difficult and requires a completely different approach to many of the levels. Many difficult sections require specific routing with point-blanking. My only complaint is the hitbox is quite large and not exactly clear, which is not ideal with the dense and very fast patterns this game has.
