How to restore all settings to default?

I can’t seem to figure out what to do after changing from windowed to fullscreen. I can’t click anything without having to make my mouse hover down and to the left of it and thus can’t click apply at the bottom of the screen to change the settings back. I was wondering if there was a way to change back to all default settings or if I simply will have to request a refund for this game.

Try modifying (or deleting) the GameUserSettings.ini located in %appdata%/Local/Tower/Saved/Config/WindowsNoEditor. Try setting the ResolutionSizeX/Y to your screen’s resolution. The files can be edited using any sort of text editor.
