About Crucial Investigation

Crucial Investigation is a text-based adult game by root, built in HTML and presented with 3D CG visuals and real porn imagery. You play Amy, a young policewoman who wants to help people and serve the public. The opening finds her summoned by her boss to start a new case at a nearby school. The game combines narrative choices, progression levels, and adult themes such as corruption and mind control.

Development is ongoing. The current build is v2.05p, released April 8, 2025, for Windows, Linux, and Mac in English without censorship. The latest update is the full Patreon version. It continues the main story through levels 66 to 69, adds a new outfit and animations, and includes scenes for street, pool, beach, gym, bar, park, school, and police locations. It also adds a doctor’s visit, Candy corruption random events, revised random events, sis and exam updates, and code refactoring.

too much pointless grind. the grind is used to pad the game between the crumbles of actual content, sometimes it feels like you are stuck in a endless loop for no meaningful outcome. there's some good ideas yes but they…

After putting up a rather harsh review of this game, I've edited it to focus on a handful of concrete issues. This game is overly grindy, with vague parameters for progress, and no way of actually tracing your steps, or…
