Finding a light switch in a dark room is a request I often hear from students. To accomplish this, we must create the 'illusion' of a dark room by creating a workaround. This example demonstrates one way to do this.
Light Switch in a Dark Room was created with Inform and has IFID 57C03664-5AAE-4D2C-B3D2-84295DD8168E. To play a work like this one, you need an interpreter program: many are available, among them Zoom
for Mac OS X and for Unix; Windows Frotz or Windows Glulxe for Windows.
