You're not missing anything, I just didn't have time to implement a way to make it affect play. I tried making the enemy's only attack in a range, but couldn't figure this out in time.
Love the game idea! It felt awesome when you figured out how to complete the level. The only issue I found is that there's some inconsistency with the actions, like sometimes I shoot over a cannon bal and kill the goblins while other time my shot slightly goes to high or slightly to low, colliding with the cannon ball.
