Small update to remove deaths from fall damage.

Death from fall damage has been removed from the game. In testing it seemed too unpredictable to reliably judge, making an already hard game even harder.
It may return at some point as a setting the player can choose to turn on or off.
This does remove some of the puzzle element of the game. Each level now has several more paths to choose from for completion. Overall it has made the game a little easier, but more enjoyable to play. Thanks to everyone Beta testing!
