Just a theory.. I feel like Bada is the main protagonist of the game.. I feel like before the game started, Bada had already completed a video game version and it had a secret code or something leading to this place and so whoever made that game made it so Bada is connected to the ending and the overall storyline of the game. So he's unable to kill the killer because he most likely already knows the true ending and who the killer is +++
I feel like the prologue where everyone starts has a really huge clue so they made Bada forget everything to make it more fair to the other players or smth
