■Story
The heroine, who had been captured by demons, is endlessly being raped by them in the depths of an underground labyrinth.
One day, the heroine wakes up to find the lock of her prison cell unlocked.
She quietly slips out of her cell, and makes her way through the labyrinthian corridors, which are enveloped in eerie silence, and unsettling noises.
Will the heroine be able to safely escape from the labyrinth?

■Introduction
"UnHolY JaiL TRPG" is an erotic trap dungeon escape game, with easy mouse-only controls, fashioned after a TRPG-style game design.
A standing image of the heroine is animated to fit the various events, adding a sense of real-time to the happenings and visually representing her status at all times.
Additionally, dozens of cut-in illustrations have also been added during events, to further visualize the scenes.
There are currently two pre-made stories/gamemodes included: "Original" and "Game Book". Alternatively create your own events or stories with the editor.

■"Original"
In this gamemode the player aims to reach a progression of 100, while overcoming (or succumbing to) various events he encounters.
Events are chosen at random, and each playthrough may differ a lot from the one before.
Points are spent to modify the heroines’s initial stats and status conditions.
These will be used to influence the difficulty of encountered events, or even change the possible outcomes.

The player will be forced to choose between multiple options for various events along the way to escape from the labyrinth, while clearing timing games called "gauge checks" that are influenced by the heroines stats.
When her HP reaches zero, the player is returned to the status setting screen, which is the re-starting point, where they may once again spend earned points to raise or lower stats before challenging the labyrinth again.
A playthrough is only truly over, once the heroines lewdness value reaches or exceeds 100, or one of multiple possible endings have been reached.

■"Game Book"
This mode is a more story-driven experience with a fixed layout in the style of an old-fashioned TRPG game book.
Just like before the heroine´s status may be adjusted before starting, or re-starting.
In this one however, the game unfolds according to a predetermined storyline, rather than in the form of random events, requiring the player to find the correct path to success.
Explore the labyrinth to find switches, items, and skills required to progress, and ultimately try to escape safely.

■Edit Mode
This allows the player to create their own events and stories or edit existing ones.
You can change various values, animations, cut-in illustrations, etc. of the original and game book, and add new stories, events, endings, etc.
In addition, illustration materials are available for use in the game folder, and players can add new event images by processing them with paint software or other tools.
Furthermore, you can change the costumes of the heroine by modifying the materials, add sound effects, change backgrounds and more.
Why not create an erotic story truly to your own liking?
