there is a 3 unit limit per trench... keep that in mind, it's very important. you can force them to leave if you first click on the switch button bellow the trench and then click on one of the three buttons that shows a unit.
the game had no sense at all, and wasn't intentional i think... anyways the good thing it was short, the bad thing it just was about randomly clicking to find things except maybe the pipe and bullet.
cool game but needs a way to show you where you are placing the piece, like a ghost image of your piece, because some times you move by mistake in other place, and if you are counting moves and time, that is helpful.
I loved the game and the golden van. What works best for me is to wait until you get the missiles, but with the best speed and armour. wth the super speed, you can play always with the shift key pressed so yuy can maneouver better. I always had a problem (i believe since my IBM xt pc) that if i press up and space, i can also press right but no left, weird. oh, and on slow motion, you have to release the up button so you can fire the missiles.
i have a comment on this game: i know policemen in my country that doesn't need to shoot at you or crash you to take out money from you ;)
