Though this take on the theme seemed to be pretty common, I like what you've done here! The controls were pretty good, and I really like how you pulled the battery mechanic. You made some good visual indicators for when Rober is outside Mars' range (Linerenderer and circle), which makes it easy to understand things. I also really liked that little run cutscene at the beginning, intensified the game and also gave a sense of urgency.
A little note on the controls, sometimes it doesn't seem to detect my jumps, most commonly when I'm near an edge or walljumping, so I had a few unfair slips here and there. The slopes could be tuned a bit as well; I seemed to have gotten stuck on it a couple of times.
Overall this is a good jam game! Best of luck to you.
