You have to get to the soul shard hidden behind the gate. You will find yourself in a hospital where nurses will stop you in all sorts of ways. Therapy of suffering no longer bode well from its very name.
Explore the corridors of the hospital to find many clues. Unbridled dancers and rollerbladers instead of nurses. What’s wrong with this place? The dissonance of understanding and what you see will clearly confuse you.
Remember your main goal. Outwit each of them so as not to fall into the clutches of a terrible nurse. She will chase you as soon as you start collecting diamonds. Can a medical worker be so vile and evil? Follow the map for crystals and teleport, open doors to other compartments to hide from the distraught girl who runs after you at unrealistic speed.
