You can hard-reset your settings by doing this:
- Type "run" into your search bar on the bottom left (assuming you're on Windows 10), open the Run program.
- Type "%localappdata%" into the Run program and hit enter
- Find the "Dead_Estate" folder in the directory that it brings up
- Open the Dead_Estate folder and delete the file named "settings.sav"
- Open the game
Let me know if that works!
