A more complex version of this project can be found here: http://scratch.mit.edu/projects/12347291/ Another interesting project! I was asked by @Oui1024 whether I could show him how to create a game that would rotate the level dependent on where you were standing in that level. What immediately sprang to mind was Mario Galaxy... So here is a first attempt at a game engine allowing for this kind of player/world interaction.
So, gravity pulls you towards the center of the planet, and the camera is orientated such that down is in the direction of the pull of gravity. You can move around and jump using the cursor keys. This could be extended to allow for multiple planets with their own gravity depending on which one you are nearest :)
