Rotate the player sprite in the editor so it is at this angle : <img src="https://dl.dropboxusercontent.com/u/49548363/playersprite.png" border="0" />
That should have the player upright at all times.
Also you can set layout angle to angle(player.x,player.y,planet.x,planet.y)-90 to have the actual layout rotate which looks fun, if you wanted.
