pretty cool prototype. at first i just wandered around, then i used the scanner, but then i realised the cool stuff did nothing for now, so i started following the marine floor looking for the highest elevation trying to get to that 970 elevation, but i think there wasn't ground at that height and the idea was for you to rise when you were done. i found following the floor more intresting than simply using the radar and heading on a straight line. maybe you could consider using the floor as the guider instead, that could be done in several cool ways probably and would make the exploration feel better imo.
