Together with Helltaker the player receives a large harem with demon girls, having previously coped with their insidious logic tasks. The indie puzzle game is made in the anime style and asks you to go through all hell to find your love, gradually winning the hearts of demonesses, solving puzzles and trying to survive.

The hero is Helltaker, who once fell asleep and had a strange dream, where the guy gets a whole harem with beautiful and minimally dressed demon girls at his disposal. The character liked the dream so much that after waking up, he decides to immediately go to hell to fulfill his dream. In the process, the protagonist invites the girls to join, but even if successful, painful sensations await him. As you progress, the gamer is asked to go through a lot of puzzles in order to get a new girl by correctly answering the question she asked. Then the demoness falls into his possession. Logical tasks are divided into several stages, for example, pushing stones, avoiding skeleton soldiers, as well as collecting keys and avoiding traps. Having reached the girl and heard the question, you need to choose the correct answer, first trying to guess her character or wishes. If the option is incorrect, the user is killed by a demon girl. It is also possible to skip complex puzzles in the menu in order to immediately meet the demoness, but with the exception of levels where you need to fight bosses.
