I'm at level 6 at this point, just by experimenting around.
Are the gauges supposed to change during play? If so, i have encountered a bug. If not, then how can I tell what I need to do in order to say move the gauge to the left?
The gold bands stay fixed. The white needles and X/Z numbers show your live state and should change, but some crossings only affect the hidden Y value, so not every move is visible. Moving left means reaching X = -1, not pressing a left key. For level 6, try W, W, S, W before the first eye.
