Ive bee playing this game for quite some time now, and Ive gotten pretty good at it. Im down to my last level on 3 stars and I have finally decided to look up how to beat the level. There is a YouTube video of the level and how to beat it. Ive followed the order EXACTLY, and still, runners or copters get through. Also, the time stamp on the screen compared to my time stamps when I play differ by 15-20 seconds by 2 minutes in. There is a delay on my runners entering the screen. Ive noticed on other levels that runners or aircraft do not always die with the same towers. Sometimes they do, and sometimes they barely get through. This makes the game really inconsistent and quite maddening to play. I build the same maze, but I have to start all over if they get through when I know they shouldnt.
