Hi Mystae,
The AI probably aren't the best presentation of the theme, but if you don't boost or fire, you can absolutely hide in the clouds and behind the Zeppelins - it's definitely advanced gameplay, but its what makes the game strategic instead of just a straight shooter in planes :P
I found the difficulty a bit hard to grasp, but about 3 rounds seems to give people enough chance to really feel the controls and experiment more with the hide-n-seek and stealthy strategic gameplay. If you get a chance, I'd love to hear how you find a second go.
