Shiren

Shiren is a dungeon crawler role-playing game built around grid-based, turn-based exploration. Its documented core activity is descending through dungeon floors, fighting enemies, collecting resources and loot, and strengthening characters. The source describes 34 dungeon environments, and its rules place weight on planning because movement, item use, and retreat all carry consequences.

Turn-based movement and enemy timing

Combat follows a grid-based, turn-based system. According to the source, enemies move only when the player moves. This makes each encounter a puzzle-like decision problem rather than a fast-paced action sequence, so the timing of each move is central to the experience described.

Weapons, shields, scrolls, and staffs

Weapons, shields, scrolls, staffs, and special items form the basis of combat. The source states that each item has unique effects and limitations. Some weaken enemies, while others provide defensive support or escape options. The description does not give item values or formulas, so the practical effect of any single item is not assumed here.

Hunger, status conditions, and hidden traps

The source describes survival mechanics that include hunger systems, status conditions, and hidden traps. These pressures require players to balance aggression with caution. The description notes that rushing forward without preparation often leads to failure. It does not explain how hunger or status effects are calculated, so those details remain outside this profile.

Randomized floors and retries

Each dungeon features randomly generated enemies and floor layouts. The summary adds that layouts, enemies, and items reset with each attempt. It also states that losing a battle costs everything the character carried, while the player's knowledge and strategy carry forward. The source frames failure as a restart of the dungeon state in which the player's own learning is retained. It does not describe any further carry-over system.

Rescue mode and progression

The game includes a rescue mode. If a player fails during exploration, they can call for help from friends or other players to continue, which the description says reduces the game's burden. The strengths section describes an online rescue option from other players that helps players continue without losing progress. The source does not specify how this option interacts with carried items, so that detail should not be assumed.

Progression is described through reaching deeper floors and strengthening characters with loot. The strengths section also states that Koppa and Asuka can be selected as playable characters.

Touch controls and navigation tools

The smartphone version uses a virtual gamepad for movement and interaction. The source says that dual search displays, step tracking, and an enhanced mini-map help players navigate complex environments. The description also says that save systems and interface design are tailored for mobile sessions, but it does not detail the save mechanics beyond that statement.

Story and presentation

A player review included in the source describes a ghost girl who asks Shiren for help, with Koppa as his animal companion, and a setting in historical Japan. The reviewer found the writing serviceable and the animation and drawings dated compared with modern budgets, while describing the overall atmosphere as appealing. These are one reviewer's reported impressions. The reviewer's account of finishing the game in about five hours over three attempts is also reported here and has not been independently tested.
