On higher levels te healing takes ages. I suggest healing a percentage of your raiders hp each second instead of just 1 hp per tick. I know you have healers, but it still takes a long time once your raiders get wiped out.
Alternatively you could implement a death timer system, for example when your raider dies it stays dead for 10 seconds and then respawns with full hp.
yay i did it!! imade it to 6000 ft.
just jump to the highest point you can get an then go traight forwart with you rocked. when you reach 195 mph stop using you rocked. as you slowly fall down go upwarts as you reatch the water. as high as you can. then go straight again and use up your rocked fuel. that must work.
