Mouse: P.I. For Hire, the noir-inspired cartoon detective first-person shooter from Fumi and PlaySide, has passed one million players across all platforms since launching in April 2026. The milestone matters because it signals strong early momentum for a stylised, risk-taking indie title, particularly after continued post-launch support and performance improvements. The announcement also reinforces the game’s growing visibility on Switch 2 and other systems.

The developers shared a thank-you message and custom artwork to mark the achievement, describing the game as a project built through “ink, sweat, and stubborn dreams”. Recent updates have aimed to improve the experience, with last week’s patch adding a balanced 40fps mode, a level revisit feature, weapon wheel upgrades and a broader control rebinding overhaul. Nintendo Life noted that the figure refers to players rather than confirmed copies sold, and highlighted its own positive review, which awarded the game 9/10.
