Awesome but difficult

This game is amazing I just love the old black and white and thats its WWI. But theres just one problem and its that the games is way too hard. Im stuck at level 22 and its impossible to complete because they give you one restore balloon and then send out 4 planes at once and massacre you. Pls make it easier I would really like that to happen.
