Cat Butler: Idle Shooter RPG Launch Update: Lunosoft’s Mobile Hybrid Releases on Google Play and ONE Store — “Ikmyeong-i” Character Collaboration at Launch

Cat Butler: Idle Shooter RPG from developers SUPER KEEDLE and HEYKEY STUDIO, published by Lunosoft (CEO Kim Bok-nam), has officially launched on Google Play and ONE Store on August 13. Samsung Galaxy Store availability completes the three-platform release for the mobile hybrid that secured pre-registration featured placement across all three Korean Android markets simultaneously — a sweep this coverage noted in both the July preview and the Galaxy Store addition update.

Lunosoft marks 20 years of operation as a mobile-to-PC publisher this year. Game Business PM Baek Cheol-min described the launch’s significance: “Cat Butler was a meaningful project where we confirmed the high expectations of global users through platform-featured selections from the pre-registration stage. Starting with stable Korean service, we will expand the service area to the entire world going forward.”

The Game at Launch

The premise remains the premise: a house cat teams up with their rat master to rescue the cat’s beloved butler (and the “Daily Churu Guarantee”) from alien spider forces. One-handed joystick control, auto-attack idle progression for standard play, and bullet hell boss pattern encounters for active challenge — the hybrid design that separates the idle RPG audience from the shooting game audience while serving both.

New content confirmed at launch:

The “Ikmyeong-i” collaboration brings the popular Korean character trio — Ikmyeong-i, Ggekkug-i, and Oljaeng-i from the “Ikkuk-jjaeng” character group — into the game as playable characters, companions, and themed content. The collaboration represents the IP partnership pathway that Lunosoft’s 20 years of experience in Korean mobile game publishing specifically enables.

Special dungeons confirmed at launch: Bounty Hunt (현상금 사냥), Golden Wing Tournament (골든윙 대회), and Random Battle (마구마구 전투), each with distinct reward structures for repeated engagement.

Offline event: A character pop-up store runs at Shinsegae Centum City in Busan from August 21 for two weeks, with collaboration commemorative reward coupons for attendees connecting the in-store and in-game experiences.

The Pre-Registration Conversion

The triple-platform pre-registration featured sweep — Google Play Global, ONE Store PLUS, and Samsung Galaxy Store — was an indication of platform editorial confidence before a single review existed. Whether that confidence converts to actual player retention and positive reviews is what the post-launch period will determine. Lunosoft has noted that the stable Korean service launch is the foundation before global expansion — the sequenced rollout strategy that allows operational refinement before the full international push.
