A new reasoning experience with AI gameplay implemented

You can ask anyone for any evidence.Maybe your rigorous reasoning will make the suspect afraid of breaking through, or maybe you will get an unexpected answer.Different from other reasoning games, "Mysterious Reasoning" has a large number of real-time dialogues. Each NPC is not just an ordinary character, but a reasoning opponent that dances with your thoughts.

A plot of 400,000 words

There are about 400,000 words of weird and fanciful thoughts, interlocking case logic, and rich and diverse characters.There are a total of 4 core cases and provide multiple possible endings (3 main endings + 20 branch endings).

Various strategies to catch the real murderer

The mandatory "evidence collection phase + reasoning phase" gameplay is sometimes a bit frustrating to play, especially when you are stuck at "Where is the missing evidence?"

"Mysterious Reasoning" breaks the linear performance flow in the classic reasoning gameplay and encourages players to walk freely on the map at their own pace, search the scene, and connect clues; case puzzles can also be solved layer by layer through different reasoning routes, with multiple solutions.

The secret to beating levels quickly is..."role playing"?

Yes, that’s “role play.”Although your profession is "detective", sometimes you have to "play" other "professions" for the sake of the truth.To make your role-playing more interesting (not just NPCs).
