I love your game. It was simple to understand but also quite a challenge.
I would have loved if the anchor would be a little easier at the start and harder the more you progress (like the area a bit bigger for the first few planets, or it takes 0.5 sec at the beginning, 1 sec later because gravity is weaker than the planets at the start). Just getting to the 1st planet was super difficult. I got to the 4th one, I missed the anchor by probably 0.1 sec and I lost it all!! Bouncing off the planets too was really punishing.
I really love the concept, I would play for hours. I think it needs a bit more balancing though!
Great submission, good job overall :)
ps. nice windows XP design, I love it
