YAY~~~THEORY TIME!!!

So my theory is that they are all players but the starter player is Bada since he just so happens to be the horror fanatic of the group and is the most suitable to being the most aware of everything.

The goal of the game is actually to "wake up the rest of the players and escape together". Bada tried it a couple times before but everyone was either doubtful, irrational or like before accused him of being the cause of it all and killing him, so he ended up giving up on the idea because of all his failed attempts and he remained the only one "awake" until he ran into Psycho-Nice-Guy (who may or may not be the actual 'first' to awake--) which would make sense if he WAS the first to awake because when the 3rd guy [Mr. Brainless] had woke up, the way he did was by entering a cassette tape into the radio which is the first scene!! But we all know the Psycho-Nice-Guy has always been the driver and always been in the front seat, so it would make even more sense that in one of the turns or the FIRST turn when someone asked to "put some music on" or to "turn on the radio" or even "i found this cassette or I have a cassette put this in!!" the first one to do so would be the Nice-Guy-Multi-Talented-Leader-Figure who can and would very well put in the cassette "FIRST" thus saving his gameplay.

The 3rd guy Mr Brainless had only completely awoken after Psycho Nice Guy LET him save his game which was before he witnessed his crush murdered and then for the second time letting him save his game after which contributed to his "test" that he wanted to try out~.

While unknowing in the first turn that Psycho Nice Guy was awake-- Bada in the same turn found a cassette and "saved the game" thus starting the regression cycle and they both continued to play the game in their own individual states until the law of probability finally matched the two up together by Bada witnessing Nice Guy kill someone so calmly. Keep in mind Nice Guy from the beginning and as well as before the game was always a sociopath so his calm, cool and collected rationale was always the same from start to finish but it's now being advertised now that they are in a never-ending game. Bada had to gain his rationale through time collected.

Everything began to work differently because Psycho Nice Guy decided to not follow the script and also Bada and him acting extremely close to one another in front of everone changed the endings~ So from now on with Mr Brainless in the mix the rest of them will now either probably find cassette tapes on their own and save the game OR will be convinced to and save the game through the influence of the "woke" players~~~
