Herd (Full)

Well, I was going to wait until a later date to finish and release this version, but a lot of reviews for the pure code version are complaining about lack of sound. So cor blimey, I added some.

Scoring:
The score you get for herding a sheep (/lost soul/hangglider) into the portal is based on the number of seconds remaining. The more seconds left, the higher the score.
Running into wolves (/angels/biplanes), which damages you, gets you points - but not as many as luring a wolf into the portal.
You lose points when a wolf destroys a sheep.
At Game Over, each sheep saved throughout play is worth 500 points.
If you complete all 20 levels, you will recieve a game completion bonus of 100000.
