Yes, I got a Zoom H1 Essential some time ago. It is a nifty little recorder. Some of the sounds you hear are a marker, a pen click, flipping paper, a wine glass, a steel cup, a Dremel, and some steel wire.
holy! gotta update the rating audio doesn't get any better than that!
edit: its really crazy, I replayed your game you really did an outstanding job on audio and otherwise!
