Developer Serious Sim has confirmed that Clean Start, a cozy cleaning and organizing puzzle game, will officially release on November 5, 2026. The title is arriving on Windows, Mac, and Linux platforms via Steam.

Quick Facts

  • Release Date: November 5, 2026
  • Platforms: Windows, Mac, Linux
  • Current Availability: Demo available on Steam through August 13, 2026

Ahead of the full launch, players can access a newly updated demo on Steam. Released as part of the Tiny Teams Festival, this build includes four distinct rooms to organize and introduces a new dusting tool. The developer has also implemented ease-of-use adjustments and refined achievement tracking based on feedback from earlier playtests.

Gameplay and Technical Considerations

In Clean Start, players take on the role of Lena, a woman living abroad who finds work cleaning and organizing the homes of others. The gameplay focuses on a calm, narrative-driven experience without time limits or game-over states, as players uncover the personal histories of clients through the items they leave behind.

While the developer has confirmed native support for Linux, Mac, and Windows, potential players should note that specific technical details—such as verified Steam Deck compatibility, frame rate performance, or Vulkan implementation—remain unconfirmed. Serious Sim has indicated that further playtests are planned leading up to the November release; interested players can join the developer's official Discord channel to stay informed on testing opportunities.
