to Vardix：Upgrading the wheel and rocket is the most important to fly farther, and the tricks combo is good for your point gaining (ground actions combo is much easier) Don't buy the helmet, and don't buy children if u let them die easily (not very profitable)
U have to keep your health enough until u reach the next town. And what is most important to complete the game is a ship, and 4 employees good at fighting...
I think it's really fun to play, but it takes a long time to get high score. And sometimes all the troops were crashed by just an unfortunately arty strike ......
