DreamControl Inc: Nightmare Cleaner is an action role-playing game set in a medieval-inspired dream world. As night falls, you assume the role of a senior cleaner at DreamControl Inc, tasked by an elderly woman to enter the nightmares of her granddaughter, who weeps in the attic. Navigate through labyrinthine dreams, battle against dark forces to cleanse the girl's haunting nightmares, collect powerful relics left behind by former colleagues to enhance your abilities, confront perilous challenges, and piece together scattered diary fragments to uncover the truth behind the origins of these dark visions.
