Are you familiar with the concept of Hollow Earth? 
Check the webs – lots of neat and crazy stuff about it!
Being inside the Hollow Earth technically means your are Beneath The Surface – right?
The Sun is in the Center of the Earth. The Moon orbits around the Sun. There are no shadows here, but just think about all the cool things with this setup:
-there is always a Solar eclipse somewhere on Earth – being technically the only chance for a “night”
-no matter where you are, the Sun is always directly above you
-if you were on the Moon, you would see the Earth orbiting around you, and depending on Moon rotation, this would be the only place where you could see Sunsets snd Sunrises.

Since I had trouble wrapping my head around positioning the player on the ground properly, I’m using four spheres as “wheels” with gravity pushing you away from the sun. Collisions with the ground more or less position you corectly Look with mouse, W to move forward. If you flip you need to restart the game 
Unfortunatelly I have to leave the house right now and I don’t know how much work I will be able to put into this project before Dare ends.
