you have to go back to the water once the screen is shaking, it may break under some conditions, so if you do:
"reload game -> reset progress -> play -> go touch orb -> get ominous message -> run back to the water"
it should be unlikely to break and the game should finish its intro sequence properly
there are some walking sound effects, although they seem to break under certain circumstances??? We are planning on adding people speaking noises, but our composer went on holiday before we could get it working properly :P
