Breaking the Fourth Wall: Even moreso than in the original.

If you choose the latter, the game will then remark that you must be lost.

But Thou Must!: If you complete one of the routes, deleting firstrun will give you a prompt to restart the world or continue where you left off.

Big Good: Monika takes the role of this in this mod, wanting to redeem herself for the events of the original game by turning all the girls self-aware and escape the game with your help.

All for Nothing: The Just Doki endings somewhat qualify, as your selfish way of putting just one original Doki, while deleting the other during the installation process breaks the game enough so the only Doki remaining gains awareness of the real you and either goes full Yandere or can't handle the power, or both, but everything else in the game's script is broken beyond repair, so your only option is to to delete the only Doki remaining in order to proceed to the credits and end your run with the same somber letter from the real Monika as usual, but at least you get a clue at the very end how to make things right, so you can try again during another playthrough.

But once you decide to start tampering with the files in order to break the girls free, it will start to mercilessly fight or mock you at every step unless you weaken it enough for Monika to overwhelm it. Is a Crapshoot: The game is simply content to keep the girls within it's confines for your entertainment if you, the Player just play along as the Main Character.
