Evaluation

Detective, Guard My Secret! launched on May 15, 2025 as a complete mystery-romance RPG featuring eight characters, live-action cinematics, hacker puzzles, and a multi-timeline narrative. The store description emphasizes it as a finished, polished product — the short description even highlights a "207-day polished script," indicating the game was developed to completion before release. Post-launch activity has been limited to routine maintenance: a bug fix the day after launch (May 16, 2025) and a quality-of-life patch on June 6, 2025 that added a skip function and next-interaction-point feature for interactive videos. No major content updates, expansions, DLC, or roadmap announcements have been made. There is no DLC listed on the store, and the developer has not communicated any plans for future content additions. With no post-launch content cycle, no announced future content, and no unreleased DLC, the game appears to have launched as a complete, self-contained package.

Evidence

Short description highlights a '207-day polished script' and a complete feature set including hacker puzzles, live-action cinematics, and multi-timeline narrative — language consistent with a finished product.

Intrusion Successful

Holy crap, finally hacked in! Who writes these lame product descriptions? This ain"t some cheesy dating sim, dude!

I"m a freakin" detective! Real mysteries here! These femmes fatales are packing secrets - hence the dang title!

Fine, let me break it down.

So you"ll meet these hot clients (photos below) who hire you for cases:

Miss Pure Sunshine: Dance instructor Liu Yuqing (body goals!)
Happy-Go-Lucky Gym Rat Streamer Li Chenyu (kinda airheaded)
Ice-Cold CEO Fang Yun (trust me, don"t piss her off)

Others on the poster? Play the game to meet "em. Seriously, it"s not all about romance!

Each girl"s got skeletons in her closet. Will you join their downward spiral or drag "em from the abyss? Hero or bastard - your call.

Pfft, I know what you"re thinking. Don"t sleep on mystery-romance! I"m badass detective Kurosawa Kaede - combines Bruce Wayne"s brains with Brad Pitt"s looks. Just trust me!

Oh wait.

You ARE me.

Dev Diary

“This isn"t about fixing them. It"s about who YOU become.”

First interactive movie from Serenity Studios. Holy hell, blending cinema with game mechanics was brutal.

Original vision? Cool detective persona solving cases while dating hotties. Reality check: We nearly died syncing film shoots with code-heavy branching narratives.

Maybe our gameplay isn"t AAA polish, but damn… we bet everything on gripping twists and complex characters. Three-month delay? Worth it to avoid half-baked crap.

Boss said: “Even virgins deserve to look sexy.” Treat this as Season 1 of our “Detective Cinematic Universe” - ambitious worldbuilding despite rookie stumbles. Your feedback? Brutal honesty welcome.

Because like our tagline says:

“Lies comfort. Truths destroy.”

Find your truth. Find your girls. Find yourself.
