Great arcade shmup fun, but nothing new to get excited about.
Is it good? Yes.
Is it worth $30? No.
Is it worth $20? Kinda but you can simply get Castle Shikigami 2 for cheaper.
I say Gamefly it and play it a few times since the replay on this baby isn't too high. It's not as hard as Ibara or Espgaluda but it's also not as much fun.
