It's a very cute game with a cute art style. The concept is very cool, however this may need a wee bit more polishing.
The music was very nice and soothing, but it was kindda disappointed when I realized that it restarts whenever I die, and I died A LOT.
Maybe the movement of the objects could've used some smoothing too.
Other than that, it's a nice and challenging game. And it's a good opportunity to teach people about astronomy and how earth came to be, so I really do reccomend that you develop this more.
