It's an interesting idea, but--I've wandered around enough. I've collected everything I could find, including the few things that were, annoyingly, hidden from the viewer so almost nothing of them were visible. It's become an exercise in frustration, as I randomly click the screen and also randomly try and use this item on that one or that bit of the environment.
I have no idea what the point is, or what I'm really supposed to be doing, so both could be a lot clearer.
