very good. I would not sit through it all but the format is done very well. I guess the point of the game is not really to play it or to sit through it but to have it running while your away from the computer. good idea i think.
Simple game, I could make some suggestions though. one would be to make it easier to stop the cars instead of having to click twice to make the car stop being the first click makes the car speed up. second would be to have the cars stop behind other cars. You stop the first car and the cars following would have a "auto" stop behind each other.
I dislike the bugs on first level coming from two directions. Most of these games start with the bugs coming from one direction. It just seems a-little to hard and you don't seem to cover the cost to build a wall or turrets in time and you end up losing all of your lives.
