stay only in chapter one (first three aircraft). they are the only ones made by the original devs and are higher quality. i haven't tested expert mode so try at your own risk

play the game have fun and then when you finish move to the next step.

cry. as the crushing realization sets in that the devs will never update this game. do what you want now, refund, yell at the devs, etc etc.

you have completed this horrid game good job. for real though id recommend making a youtube video addressed to the devs and make guides or otherwise. if enough people do it we might be able to get heard please id love to see this game reach its potential.
