Cosmo Cat: A Cozy Desktop Idler

Turn the Time You Spend with Your Cat into Constellations

Spend time with your own little space cat and turn each day into a constellation. Set out on expeditions with friends and meet the guests who visit your universe.

1. Each Day Becomes a Constellation

At the end of the day, turn the time you've spent into a constellation unique to that day. Completed constellations are permanently saved to your calendar, creating a visual record of how you spent your days.

2. Free Roaming & Starlight Expeditions

Your cat continuously drifts through space, discovering Stardust and Constellation Fragments along the way. When it's time to focus, set a timer anywhere from 15 minutes to 1 hour and embark on a Starlight Expedition. Whether you're actively focusing or simply leaving the game running in the background, the time you spend becomes part of your in-game journey.

3. A Little Cat by Your Side on the Desktop

Switch to the compact window and place your cat anywhere on your desktop. Your cat quietly floats through space inside the small window, and hovering your mouse over it reveals a radial menu. Access the timer, calendar, and customization options whenever you need them without interrupting your work.

4. Create Your Own Cat

Mix and match eyebrows, eyes, mouths, patterns, and accessories to create your own unique space cat. Use the Stardust you collect while playing to unlock new customization options.

5. Build Your Own Universe with the Constellations You Discover

Completed constellations can be freely placed throughout your personal universe. Move and rotate them wherever you like, and adjust their colors, sizes, and more to create a universe that's truly your own. As your daily constellations and collected constellations accumulate over time, the once-empty universe gradually fills with memories of the time you've spent.

6. Explore Together with Friends!

Invite friends into your universe, spend time together, and set out on expeditions to discover the same constellations.

7. Guests

Meet the guests who occasionally visit your universe. They may stay for a few days before heading off again, but don't be too sad—they might come back to visit someday.
