The game is great but there is some issue with the goldmine time calculations...... If one iron bar decrease 8 minutes then 15 bars should decrease 2 hours.... But it only decrease 1 hour and 25 minutes when I deliver full trolley of 15 iron bars.... And the helicopter controls are trash. The goods keep swinging in the air and it is very annoying.. U should give a control to tight or loose the carrying rope. Plus the cars tyres slip so much even on plain ground Make them a little bit more stable
