I think this is a really creative take on the theme. I love how you have to free the rover, it's pretty adorable. :)
Once I figured out how to play, I really loved it! The puzzles were pretty fun. In your post-jam version, maybe you could add a restart button, and give the player a few seconds before the rover starts moving? I dunno, it was a good game and I'm trying to think of feedback. Good work! :)
