If we have free will it is down to us to sort out this sort of shit, irrespective of His existence or not. If we don't have free will then we are not responsible for what happens. If God gave us free will He is still vicariously responsible for what we do with it, so if God exists He IS ultimately responsible for the fate of the amusement park, and all the inhabitants thereof, He created.
EDIT, added below.
So calling on God to help us is a waste of time and effort as he should have never let us get into this shit in the first place or he doesn't give a shit now that we are in this situation.
So either God does not exist or he's a completely psychopath and in the later case he can go fuck himself. And I'd say that to his face if he showed up right now. But as he would be a psychopath he wouldn't care any way.
