Stuck tanks have been fixed, its very hard now. good luck!
Thanks a lot, that is really really amazing. The tanks are dangerous with good aiming skill. Best to avoid. The helicopters not so much. No cheat is currently needed: You stay directly under them or simply dont move at all. They never hit me and only hit each other in the air. The more the better for me. After a while I avoid the jars completly to collect more of them. They do all the firework themselves and let the lives rain on me... :)
They move like stupid air planes, maybe they should hover, strafe, stop or move even backwards and act like real helicopters. Maybe I am asking too much... Currently the only limit is my computer performance. After a while the flood of moving objects is limiting the frames to near zero. So many lives raining from the sky, you can ignore the tanks and diying is nearly impossible.
