Pretty good, but not absolutely fantastic. There are a lot of “huh?” moments, and the endings weren’t really satisifying. Too bad. But then again, it’s not like the writer was the one that wrote Saya no Uta or Kikokugai (same company, different writer). When you complete one of the Ignis true endings (there are two), it unlocks the path to Kaze no Ushiro wo Ayumumono (that name is much too long). The parallels to Tsukihime are quite amazing.
