Good game! Make a sequel where you try to CAUSE accidents! XD Also, more levels, add drunk drivers who do weird stuff when you least expect it. Some levels could have cars that want to turn, so they have an arrow next to them pointing the direction they want to turn. I love this!!!
I like the music and I like the tower abilities. I always start with a machine gun and add a rifleman or an electric, then I mix and match, freeze towers are good, I don't like snipers, flamethrower looks too risky to even try.
I liked the story, voice acting is good, moving the camera around would be nice, to see more of the characters, but not needed and would probably be REALLY hard to program, but what do I know about programming... 4/5 because although I like the story line, there isn't much interaction from the player, but keep it up, can't wait for the next parts!
