Bertie's Box Factory
	
	[hide]
	Instructions
	
		- Bertie the blue dot is trapped in the box factory where he works.
			Help him escape by finding your way to the Finish square in each
			room (marked by a green 'F').
 
		- If the exit is not lit up you must activate it by covering all the
			pressure pads (marked by a dashed red outline) with boxes. Note you
			can only push one block at a time.
 
		- There may also be holes in the floor; these can be bridged with
			boxes.
 
		- Controls:
			Arrow keys: move Bertie around. (Note: on low resolutions
			using the arrow keys may result in scrolling of the page; you can use
			the W,A,S,D keys instead and/or hide these instructions.)
			Z: undo last move (max 20 undo steps).
			R: restart level
		 
		- The game has been tested on (and therefore works with) Opera 9,
			Firefox 2 and Internet Explorer 6+. If it does not work for you, make
			sure you are using the latest version of your browser.
