Mouse Work

Nitrome began working on the game before the mouse feature was officially revealed, and based the game's concept on industry rumors and a tease of that feature present in the system's announcement video on 16 January 2025. They did not formally receive a software development kit from Nintendo, and used Joy-Con duct taped to computer mouses to prototype and develop the game.^[1] According to Nitrome founder Mat Annal, they used their experience in creating browser games to make the game very rapidly.^[2]

Nitrome cited Pico Park (2016) and Part Time UFO (2017) as inspirations for the game. Several outlets also drew similarities to Snipperclips (2017), another indie game with a multiplayer focus that was released as a launch game for the original Nintendo Switch.^[3][2]

The game was revealed on 7 April 2025, a few days after the console's unveiling during a Nintendo Direct on 2 April 2025 showcasing the console. While no release date was revealed, Nitrome expressed their desire to release it "shortly" after the Switch 2's launch on 5 June 2025.^[3][4]
