I really like how navigation and exploring is done! I also like how you can set waypoints, but if you don't manage the speed well you can overshoot and then orbit around the target point.
I only managed to get the treasure in the SOH region. One thing that I was having trouble with was the CAH region treasure. It's kind of hard to measure 90 deg from theta off your radars on the left since it doesn't give a precise measurement of where theta is to you. I kept missing my 100 units from the crater.
