Hear me out. I think they're all players.
but first off...
RULES OF THE TAPES
- Tapes = save files/load point
- Tapes only reload if they were played before you died
- Faulty tape = faulty load point (i.e. Hyungshin thinking he's some spiritual guy that one time)
- Tapes can be marked AND THESE MARKS WILL NOT BE OVERWRITTEN. (ex. Yongtaek's smiley tape, Seongchan's check tape)
- The MOST RECENTLY USED TAPE of a player is considered their latest save file, regardless of markings.
PLAYERS:
1. Bada
- I agree with another comment that Bada probs has another tape with his old memories, but it's been lost for a LONG TIME.
- Bada DOESN'T mark his tapes, which is probs why he lost his Main one
- Whatever tape Bada used to replace his lost one might've been Doha's Main tape, hence why he knows he's in a game, but not much else
2. Seongchan [Main tape = tape with check, but no confirmed save file info]
- Since he's Bada's cousin AND has a marked tape, he probs also got numb to dying, WHICH IS WHY HE'S NORMALLY THE FIRST TO DIE. He doesn't care anymore.
- Him dying early is why he tag teams with Yongtaek. Yongtaek does double the work if Seongchan dies (lazy ahh)
3. Yongtaek [Main tape = smiley faces w/ "The End"]
- Was likely dragged into this freaky ahh death loop by Seongchan
- Joined AROUND THE SAME TIME as Bada
4. Hyungshin [unknown Main tape]
- His OG tape was either faulty or got completely wrecked
- His wrecked tape data is probs why he's a himbo (or he's just naturally that way)
5. Jaeseob [unknown Main tape. full theory, no confirmed info]
- His tape/save file is probs the most secure and hidden
- His chronic complaining can be explained cuz of HIM HAVING HIS COMPLETE MEMORIES FROM BEFORE THE GAME
- Might be the only player remaining who still remembers the ACTUAL way to end the game
6. Doha [unknown Main tape]
- Might be the newest player
- Clearly has practical and intellectual experience with horror
- Like Bada, he doesn't mark his tapes, which is why he's likely not using his Main tape with his pre-game memories. He might've found Bada's Main tape, which could explain why he's so into Bada.
RULES OF THE GAME (that we know so far)
A. Dying is not an escape
B. Different ways of dying = Different "endings"
C. Solving puzzles to reach certain areas (AND THEN dying) counts as a new ending
D. The killer normally appears when players trigger a death flag trope
E. The killer respawns unless Doha kills him for some reason, idk why
F. You can only save using casette tapes (see above)
If anyone else has stuff to pitch in/need me to edit, drop a reply.
