How it feels

A mentally demanding detective game where you piece together clues under the grim threat of nuclear terrorism.

What players say

Players describe a logic-grid deduction game where you analyze suspect movement logs like a detective. The randomly generated cases offer replayability, but many find the UI clumsy and tedious, requiring excessive clicking. The difficulty is significant: misplacing a single clue can force a full restart, and some puzzles feel illogical. Opinion splits on whether it is brain-burning or mechanical.
