What is Cosmo Cat?

A cozy desktop idle game where you spend your days with your own space cat, and the time you spend together becomes a constellation.

✦ Your cat quietly floats in a corner of your desktop while you work or study. ✦ Need to focus? Set a timer from 15 minutes to 1 hour and head out on a Starlight Expedition. ✦ At the end of the day, your time becomes a constellation and is saved to your calendar. ✦ Dress up your cat, and decorate your own universe with the constellations you collect. ✦ Invite Steam friends into your universe and explore together, up to 4 players. ✦ Guests drop by now and then, depending on how you decorate your universe.

If you're enjoying Cosmo Cat, we'd love a quick Steam review! It really helps a small team like ours.

What's next

We want to keep shaping Cosmo Cat together with you, sharing ideas and adding new content and updates along the way! If you run into a bug or have an idea, let us know in the Steam discussions or on our Discord. Cosmo Cat Discord

Thank you! 🐈 DustyNifty
