it's a fairly laid-back shoot 'em up, there aren't many bullets on the screen. The size of the hitbox seems a bit excessive to me; however, there's the ability to reflect bullets about to hit your ship, with a very short cooldown (approximately 1-2 seconds). Using a controller makes the game very suitable for beginners, and for the more skilled players it becomes a shoot 'em up to relax with.

During boss fights, the quantity of bullets on the screen increases drastically. The third boss annoys me a lot with its tendency to traverse the perimeter of the screen. On the contrary, I enjoyed the other ones; the last boss, Duoss Core Complete, is the one I have a platonic love for.

The three available ships, to choose from at the beginning of the game, differ significantly in firepower, special attack, and speed. They can be interpreted, in my opinion, as an easy, normal, and hard mode. The green one is very slow, and its firepower is kind of on the lower side, making it not a good combination. I would call it the hard mode of the game, but in an annoying way. The blue one is perhaps too powerful, especially because the time window available to reflect incoming bullets is very long. It's effectively an easy mode, thanks to its special attack that can almost immediately eliminate any boss.
