Flight from Wish Land

I know this is crazy, but I have to give it a try... The main entrance is locked and can't be barged or pried open. Climbing the wall doesn't work. No matter how much I climb, I never reach the top. I have to risk it all to get out. I've broken the rollercoaster track right at the top of its highest peak. If all goes according to plan, the car should derail at high speed, sending me flying right out of this cursed theme park! No matter what, I have to escape. I want to go home...
