Try using the other way of escape (there are 2 ways) and don't miss anything you can click on, after that just don't resist
Viewing post in anybody know how to get this cg?
There are two exists which the game tells you at the start of the dungeon and labelled as (!) for you to know. You can either go an easy way and fight through a bunch of moles/wait until the moles knows you've escaped (you spent too much time) or do some "water works" to be able to go through the other one.
Goodluck, I can't spoil more from here.
