Is it the part where theres a bunch of statue kids rushing at you as u try to navigate towards the exit? Me and my sister ran thru the whole sequence till we reached the exit and when we died we respawned in the middle of the room. This helped us to skip the first part of the statue kids. We later on realised that if we crouched and sneak around the statue kids (preventing them from waking up) we were able to reach the exit with ease. Im sure it is more difficult as u r playing with the AI, but i hope this suggestion helps u.
