The Somme but reversed

MY FIRST SHOOTER GAME! PLEASE READ ALL OF THE INSTRUCTIONS BEFORE PLAYING!!!
this is a two person shooter game in which you and your friend try to shoot down as many German soldiers as you can (the German soldiers are made to look like the top view of a 1914-1919 German war helmet. I apologize if they look like roaches). here are the directions.
The sandbags are all 25 hp, for a total of 100 hp. for each second a German soldier is touching the sandbags, the sandbags lose one health point in total. Try to kill as many before they flood the trench. Try to be the first team to get 1000 kills. 
Directions:

American soldier:
Up and Down arrows to move up and down.
Right arrow to fire.

British soldier:
W and S keys to move up and down.
D key to fire.

Enjoy!
