Thank you for the newest excellent update! You're on the right track!
May I request some additions for future updates, if not for Classic version then for Recharged?
1. Aircraft collision - can you make aircraft to have a "Health Bar" instead of just killing it instantly at every slight touch with obstacles? Say, you start with 100% health, you collide with the gate at 5km/h so you spin and rebound slightly in random direction and your health is decreases by 30%, you collide at 10km/h, you rebound harder and health goes down by 75%? When you're lower than 0% - you "Crash". Use velocity vector to calculate the values and direction of rebound.
2. Level generator - why 5 gates? Why not make adjustable value, like from 2 to 10?
