A bug causes the sprites not the show up, fixed in V1.2 released the day after.
File name is saya_cn.rar.
Known bugs: two minor characters' voice over are not playing, the text in one ending is not displaying correctly (also in V1.1).
File name for the V1.2 is saya cn [raw]v12[/raw].rar or saya_cn_v12.rar.
