Hell Escape

Level 1/"Hell" does have sound effects. However they are don't seem to play in the web version for unknown reasons.

If the objective of the "Heaven" level is not clear please read below. 
To complete the 2nd/"Heaven" level you need to run all the way to the side of the platform (either side works) and find a working path through the clouds.
