Playing with several keyboards and mice? Press End once everything is in place to give each window its own cursor.

Handler notes

IMPORTANT: IF the game starts fullscreen press alt+enter on first run, not needed after that. Also recommended to use your mouse cursor for menus instead of gamepad.

Sadly the game doesn't scale well in anything besides 16:9, so vertical or horizontal split will have menus cut off.
