Awesome and chill experience :)
The overall atmosphere created with that skybox and music is really relaxing, and i had fun doodling random madeup constellations, the fact that you let the player name them is the best part :p
and the planets discovering is also really cool where you have to use the notes to locate them with the telescope,
on that, not sure if it's a bug but it was cool anyway, one i zoomed and discovered the 1st planet the zoom level stayed outside the telescope so i was able to see the others without the clues
Anyway, beautiful entry :)
