The film genre feels very fantasy, like most Japanese films. The start of the game starts right away, without any character building. Flashback transitions can be confusing at times. In addition, the flashback should have been longer for the sake of character building, but it turned out that the flashback was very short without giving the audience room to feel empathy for each character. So when someone dies we don't feel emotional about their death. In addition, there are some unnecessary scenes such as interviews with professors on television, etc. For visuals, it's okay even though it's still too rough, but that's understandable
The advantage of this film is that it seems to be a deadly game and can invite the audience to think about how to end the game.
For those who really like fantasy films with horror thriller genres, this film is quite fun and still worthy to watch
