My best score is 43!
The earth art is SO BEAUTIFUL, it really makes the game feel special to have it be the centerpiece and even be animated.
When I loaded the game, I wasn't quite sure what to do or what the controls were as there was no instructions, but it was simple enough to become intuitive enough once I started going. And of course the title is a hint :)
A little bit of sound would really make this game. You've got a solid visual vibe for sure!
