Remvoed inheritance of the onStart method, as not being used.
Moved game screens to their own package.
Added a world variable to allow for player placement to be correct.
Changed the game to draw the background as 2*1280, 2*720 + 100.
The extra 100px to the height allows a ground part to be drawn.
Kept the old 1.png to 1.bak if the camera is going to be reverted. (1.bak.txt notifies this)
