That was pretty fun, I like the concept. I have a bit of a moth problem where I live, so I actually enjoyed gathering a group of moths then purposely flying them into a zapper, kind of satisfying... I know that's not what I was supposed to do, but moths haunt me haha.
I was actually pretty impressed by the fact that you have a fully implemented settings menu... with things I wouldn't expect (saturation etc). Minor thing - one suggestion to make the sliders look a bit nicer is to use sliced images rather than stretching the image to fill the slider.
Great job!
