What an interesting way to implement turn based bullet hell. Rather than fearing the oncoming wave of bullets, it feels good anticipating them and rushing headlong at them. The player is so powerful in this context, and that makes it quite fun. Given the player's infinite time to react and their abilities, the challenge is not quite there in this version. The game was just starting to play with enemy variety and density towards the final floors, but so much more could be done. The music set a great atmosphere, and worked well for something turn based and more cerebral in gameplay.
Also, it sure felt like stopping time every turn. Combined with throwing knives, the similarity to a particular maid cannot be denied.
