I found this game really damn corny and in-your-face with its message (WAR IS BAD WAR IS BAD WAR IS BAD WAR IS BAD WAR IS BAD). Really, we don't need to be told this, we already know all this.
However, the mechanic of not being able to do anything but shield the family was actually a cool idea. I could see this work as an actual game, but it's wasted here.
2/5 for aesthetic and the soundtrack.
Guys, you just have to do the route fast. If you're too slow, it resets to 10 then rebuilds back up to 30, losing you points. So find the longest route, and quickly go through it. That's how you get Golds.
