Great effort! Those last 2 levels were hard to beat but worth. The game was smooth and simple, and most levels felt unique.
Now, the music you used was so perfect for the game. But it kept starting again whenever I died or started a new level! So it turned from an epic feeling, into a repetitive and annoying thing that kept restarting when I died. Which is such a shame. If you ever update the game, I recommend making the music continue throughout the whole game without starting again :)
Also, if you'd like one other tip, have a line that shows the direction the player will jump. When the planets are moving fast it can get quite frustrating judging where the player will start going. And the player's movements around the planet not being very precise add to this as well.
But overall, I enjoyed this game :)
