Target Skydiving

This is a simulation of a real world skydiving jump to a target. You can experience and improve your skills to plan and perform a target skydiving jump. Please feel free to review the application. Any suggestions how to develop or improve the game are welcome.
The game starts with preparation where you are given all the essential information to jump safely: altitude, flight accuracy, wind speed and direction, parachute speed.
Next you are lifted in an airplane with open door, ready for the jump at the determined altitude, speed and flight path approaching the target. You decide when to jump and open the parachute.
Deploying the parachute gives you two handles: L and R to steer the parachute. Pulling down L rotates the parachute to the left, pulling down R rotates the parachute to the right. Pulling both ropes down decreases the horizontal air speed up to 0, moving them up increases the horizontal air speed to the maximum for the parachute.
Your vertical speed is about 5 m/s. And your ground speed and direction is determined also by the wind.
You are given readings of your altitude and: speed of flight before you jump or time in seconds after you open the parachute.
At the ground near the target you have a red balloon in the form of an arrow. The arrow points to where the wind blows from. You must try to land always against the wind, otherwise you risk to get injured.
The airstrip seen from above is located to the North of the target.
When you land you are shown a measurement of your position relative to the target. If you hit the target in a range of 5 cm from its centre you receive a measurement of 0. Otherwise you receive a measurement of the distance between your land mark and the target in centimetres. If you land beyond 5 metres from the target you receive 500 regardless of the actual distance.
Your results are grouped in a series of 6-10 jumps and the average is calculated.
Your final result is the average of all round's averages. The less you get the better is your result.
Only the best results are stored. If your result is in this group you are given the option to save it.
The game lasts for 24 or 72 hours, then restarts. During this period you can make as many jumps as you are able to. However you should take rests to watch ads, between the jumps and also take care of your health and penalties.
You have various options during your preparation and after the jump, which are activated by watching ads.
Therefore you need internet connection to be able to use them. Otherwise you get a random selection of relatively adverse circumstances.
To be allowed to make a skydiving jump you must have health > 0 and penalties < 10.
