amazing so

soo cool

Beautiful game

The game is beautiful because the planets and black holes are so cool but the only problem for stars is that it can’t get stuck into a black hole properly and that’s why it’s four stars and also the planets look so cool and the stuff that you can unlock planet by doing something like you have to crash several asteroids to form the moon is really fun but the big problem is at the watch ads to get more planets but you can get the original game of it but my dad won’t let me so that’s why.
