Thank you, and thanks for the feedback! Have to admit I struggle with all keyboard+mouse game controls, so working out a mapping was a bit hit and miss. I totally get what you're saying about Q/E -- that goes on the list for the next bugfix release. & at the very least I'll put a mouse sensitivity adjustment in. (Fully mappable keyboard controls are on the long-term wishlist. Input mapping and UI work are possibly the most painful aspects of working in Unity.)
