On my initial test drive, I accidentally put it in 6th instead of reverse and stalled it. (6th is where reverse was on my '14 Fiesta SE) It would only move in idle, as in nothing whatsoever happened when you pressed the accelerator. The service guys reset the computer with some button combination, and everything was right back to normal afterwards. I'll bet that your car is fine. The computer is pretty amazing at self-preservation.
