Hello,
It was a hard decision in your case, but I have decided to remove your game from the jam. I'm sorry. I will tell my reasons below:
1. When you said you were doing a visual novel, I thought you meant a visual novel game, which is a visual novel where you make choices to progress through the story. Your submission is just a story. There is no game at all. The "player" has not even one single choice. Ultimately, this is a game jam, and your submission is not a game.
2. Your submission does not exactly follow the theme. The character isn't really under a delusion, rather he just has amnesia. He doesn't know who he is or what's going on. The only belief he has is that a monster is chasing him, and it is not made clear to the "player" at all that this isn't true until the very end. The player doesn't know what's going on, and so doesn't know if it's true.
For these two reason, I believe your game doesn't fit the requirements of this jam.
I'm very sorry and wish you the best with further development of the project.
