The noir-style, animated detective first-person shooter has drawn attention for its distinctive art style and risk-taking design, and the team has continued to support the game with frequent updates aimed at improving performance and player experience.
In an official statement accompanying the milestone announcement and new artwork, Fumi and PlaySide said the game had reached over one million players across all platforms and expressed deep gratitude to the community, describing the project as a handcrafted story born of long hours and determination and thanking players for their support.
The announcement included custom artwork created by the team as part of that message.
The milestone arrives after a recent content and performance patch.
Last week the developers added a new "balanced" 40fps mode, alongside a level revisit feature, improvements to the weapon wheel, a control rebind overhaul, and additional quality-of-life changes.
Those updates followed the game’s initial rollout in April 2026 on Nintendo Switch 2 and multiple other platforms, where it has continued to attract new players.
The title has received positive critical attention since release.
In a published review, Liam Doolan awarded Mouse: P.I. For Hire a 9/10, calling the game a bold, risk-taking FPS and praising its animated noir approach.
The steady cadence of patches and platform support has reinforced the developer's commitment to refining combat, controls, and accessibility after launch.
For publishers and developers tracking indie success on next-generation handheld hardware, Mouse: P.I. For Hire represents a noteworthy case of sustained post-launch engagement and a cross-platform player base exceeding one million within months of release.
Fumi and PlaySide continue to iterate on the experience with patches distributed through storefront channels such as the Nintendo eShop on Switch 2 and equivalents on other platforms.
Players can expect further fixes and tweaks from the team as they refine performance and feature parity across platforms.
The official milestone statement and accompanying artwork remain available from Fumi and PlaySide as the studio thanks its player community for reaching the one million mark.
