Well i don't know how actually game works however you must actually see floors (like murder scene) to determine the killer. Even if game does't work like this you can still make like hidden door which are not visible and the only one which can figure it out then he can see real floor (his/her fake momories dissaper)
Yes they did have fake memories maybe you didn't watch it until the end?
I have only watched anime so maybe they did changed a story a little anyway in the end when they show the truth they do mention about amnesia and also about fake memories or it could be a illusion to think that they have fake memories
『I like 2nd version more mostly cause of 1.Gym is also used for Principal's speeches so in "1" they will have to go all the way left for that, 2.Guys Toilet in "1" is all the way on the opposite side of the school from Gym while Girls one is right nearby, 3.Toilets are TOO BIG in "1"!! They are 6x10 meters each while in "2" I made them 4x5 meters...』
『And I like 1st version cause..... Cause.... Is there even any reason to like it..?』
