Awsome game! You have done very well creating the walls! I know actionscirpt, and also how hard it is to make games like this. And I still havent figued out how you made the shooting! I mean, make the line stop draw if it hits a zombie. Genius! 5/5
I liked the character movement, but the enemy ships are moving too fast.
Make the stage a little longer in height, make the enemy ships move slower and make a life bar.
