I found myself getting a LITTLE confused on how to move forward when two planets both seemed stuck at about half enlightenment. I eventually figured out that I could force it to start moving if I brought levels out of balance and then rebalanced them, but this also caused some planets to temporarily die. Also, most of the planets seemed to balance themselves out without any intervention. Maybe you intended this? It's not necessarily a bad thing, just a tad confusing and definitely took away some of the challenge.
I think you could benefit from having different planets start at different balance levels, rather than all starting equal. That way all of them need some modifying to reach enlightenment, encouraging the player to prioritize and move quickly. I would also love to see more resources introduced as the game progresses (I only played the first 3 levels so apologies if this is already the case).
I think the visuals were both pleasing to the eye and conveyed important information quite easily, so kudos there. Overall I really enjoyed it, I was just a little confused at times and sometimes it felt like I didn't really need to play the game to succeed. Tweak the difficulty balance a bit and I think you have a really, REALLY solid project. Nice work!
