level 13 is easy. you have to kick the plant up onto the ledge. to do that run until you are on the left side of the orange button. then you take a running start at the plant and kick it. press the orange button and the plant will suck up the hat and toss it into the goo. simply jump on the ledge, and throw away all of your body parts except your head. ad let the plant shoot your head towards the hat
not as good as 1917...First of all, the graphics (in my opinion) were better in 1917. Second, there were almost no strategy in this game. Third, it was too easy for recruit and regular, but impossible in harden (can't get past level 2, the enemy just keeps on stacking up behind cover so that i cant break through)
