It's an alright concept.
The idea behind the game is fantastic.
I just find there's a really steep curve straight away. After the first 3 easy levels, you suddenly throw some really challenging curveballs, and I'm finding myself stuck time and time again on them. The music is rather soothing, which was a good choice, and I love the gravity slinging idea, but you've just made things too difficult too quickly. Without an option to continue straight away, like another user has already mentioned, I find myself questioning whether it is worth continuing to push through or merely leave the game.
