i found the negative zone!
after just getting into the second area, my fuel tank busted off; so I used the boosters. next thing I know I'm flying backwards and passing the divider again, backwards to a cheerful "Welcome to 'Hello!'" What did I just do?
The only issue for me is that upgrades get pretty pricey. After a while, you're just repeating the same exact run over again, to get enough resources for that last upgrade.
when i no more have feul the plane jumps back!!!
This game is Boss
