Heavy Recyclable Rocket

Highly programmed rockets.
Rocket launch and thruster retrieval are both automatically controlled.
The first stage thruster first slows down and then lands on land. The secondary thruster lands into the ocean through a parachute.
Be sure to follow the following precautions, otherwise the launch may fail
1.Need to modify the physical distance to over 350km
Modification method:Modify the "setting.xml" file
Windows:C:Users[Your User Name]\AppData\LocalLow\Jundroo\SimpleRockets 2\
Android:Android\data\com.jundroo.simplerockets2\files
set physicsDistance="10" to physicsDistance="400"
2.When the frame rate is too low, the rocket may fail to launch
3.You cannot exit the game during launch, otherwise the rocket will not be able to fly in the correct direction when entering the game again
