Seems daunting at first, but when you get the hang of it its actually really simple and fun. Great game
A few design things though, I was able to do the entire mission without worrying about the battery, since I had the solar panels and RTG up during the day, and RTG during the night. Also didn't think there was a necessity to have lights on at night, so maybe you make it darker at night to make it more necessary. It was also very easy to avoid overloading the batteries. Maybe some enemies/aliens to watch out for on missions haha, could be cool.
The SFX was very well done, and the trails are also very impressive. The graphics, fun, and controls were the categories I felt this game really shined in.
Expanding on this game can be super worth, if you decide to do so!
