Yes, open the exit door

The three Emeralds flash a bright green and you hear a loud crack! Slowly the iron doors creak and groan as they open under their own power.

Ahead of you there is a short hallway. At the end of it is a set of stairs leading up. A bright light shines down from above, beaming down the stairway.

What was up there? Was this your path back to life? Would these stairs lead you to the real world? Was this all a cruel trick? Would you go up only to find yourself in Lord Grim's clutches once more? Or were there more levels to this dungeon?

You did not know.

You had defeated this level of Lord Grim's dungeon. It hadn't been easy but you had conquered it.

You look back over your shoulder and think of all the rooms and all the creatures you met. There were challenges but there had been some good times as well.

You look up to the ceiling and say. "I hope you were entertained!"

You take a breath, set your shoulders, and walk boldly in the only direction you could. Forward and up.

(Congratulations, you finished the dungeon!)
