At the toy store the kids can buy a monkey or balloon, the monkeys want to be bought and so do the ballons. Th kids always pick ball. Thats why there fighting.
i also found a glitch, if you walk over to something then use pick up. you can click the undo walk button and you keep the gun you pick up or the bomb stays defused and you can do your turn aain.
it would be good if when you first start you select what type of soldiers you want. ie. sniper, heavy gunner. You could still equip all weapons but it would yeild advantages with different types like extra accuracy if you pick sniper. Also it would be good if you could see the range and statistics of the guns not just a description.
