On the screen in the credits where that game company has their url on the screen, and there is no red food piece to go down another level, grab the food piece under the url, not the other one!! Once you have done this, move your creature to a corner then set your Vita down and use the L&R buttons to reset the tilt. Now, just leave the Vita alone for 5 minutes. I did tap the screen when it dimmed to make sure it stayed on, and I still got the trophy, so I believe as long as you don't set off the accelerometer, it doesn't affect it.
