To open Peaceful Mode you need to finish the game with all three endings.
Three Endings
Bad Ending: Simply completing the game will lead to the bad ending. Just remember to choose "Refuse" when Mita asks you to stay before going to the basement in the beginning of the game.
Game Over Ending: If you open the safe in the basement it will trigger the game over ending. The code for the safe is 4970.
Good Ending: You need to end the game first with Bad Ending to be able to get this ending.
On your second play do this stuff:
- Play a game with Mita on TV.
- Accept the sauce and try it.
- Don't look inside the vent in the bathroom.
- At some point in the beginning of the game the "I love you" on the refrigerator will fall, pick them up and put them on their place.
- Don't look inside the oven while looking for Mita's hairbrush in the beginning of the game.
After having all of this done, when Mita asks you to stay before going to the basement, choose stay to get the good ending.
Release Date
