Scratch | Attack of the Snowmen | NORMAL

The naughty elf has been at it again. This time he has been changing the Attack of the Snowmen game.

Here's a video of how the game should work. There's a link at the bottom of the page to the broken code for you to try and fix.

Here's a list of bugs, can you fix them?

1. The game over sign doesn't show up at the end of the game.  
2. There should be five snowmen in the game.
   
3. When shot, one of the snowmen turns into an elf rather than a melted snowman.
   
4. The game ends after the music runs out.
   
5. The sight doesn't follow the mouse.
   
6. The space bar doesn't fire.
   
7. You lose points when you shoot the snowmen!
   
8. One of the snowmen doesn't disapear at the end of the game.
   
9. Does not show the correct background.
   
10. You should get more points for shooting a smaller snowman (The elf broke this part before I could record it).
