Hey do that!
Gravity games are possibly my favorite type of game (Outer Wilds, Mario Galaxy), so I really enjoyed getting to play around in here, and it was super cool to see some of the functionality in place. Great work on the art, and getting the gravity system working. It would have been nice if there was something to do, but I still enjoyed getting a look at this stage in development. With some work, you could definitely expand this into an awesome game. 
I did manage to fall into the planet, so the physics might need to be ironed out a little, but that's the type of stuff I enjoy seeing in early game development. Great work!
