Thanks for playing and thanks for the feedback!
I really like the idea of being able to walk outside of the rover after the power runs out. I kinda want to stick with the idea having unmanned vehicles, so it could always be smaller robot. I imagine something like a bb8 cruising around the area for a bit would be pretty cool.
There is also the one upgrade that I didn't have time to implement - a drone that can fly over mountains. The idea was that it could perhaps place pylons for you. Or it could just be a way to see if there are any energy sources / things to discover ahead of you.
Again, I really appreciate the feedback :)
