Cosmo Cat pairs idle mechanics with personal reflection: your desktop cat drifts through space while you casually log daily moments that transform into constellations. The game emphasizes quiet companionship and gentle progression rather than aggressive optimization, making it ideal for players seeking a meditative idle experience that doubles as a digital journal.

Cosmo Cat v1.0.3 Patch Notes

17 days ago
'First Makeover' achievement fix - Fixed an issue where the 'First Makeover' achievement did not unlock after changing and applying your cat's appearance. - After updating, change to a different appearance and apply it to unlock the achievement. You do not need to purchase any items again. Fullscreen constellation display fix - Fixed an issue where passing constellations were not visible during free swimming in fullscreen mode. - Constellations now pass within the visible screen area even after switching to fullscreen following a long period of free swimming in Mini Screen mode, or when zoomed in closely. End-of-day display fix - Fixed an issue where guests and party members appeared to pass in front of the UI during the end-of-day sequence.

Cosmo Cat v1.0.2 Patch Notes

18 days ago
Missing constellation fragments fixed - Fixed an issue where fragments of First Voyage, Trace of a Nebula, and Weekly Sky were missing from the list of obtainable constellation fragments. They can now also be obtained through Starlight Exploration and free swimming. Mini Screen improvements and unintended behavior fixes - Added the 'Mini Screen: Always Show Timer' setting. - When the timer display is enabled, exploration and free-swim timers remain visible without hovering the mouse over the Mini Screen. - Using the mouse or keyboard while free swimming in Mini Screen mode no longer automatically returns you to My Space. Cat appearance and reaction fixes - Fixed misaligned eyebrows, eyes, and mouth on the supporter cat skin. - Customization previews now reflect each skin's facial feature positions. - Improved the cat's gaze so it looks more accurately toward the mouse cursor near its face.
