Mittens, a cat burglar caught in a quantum experiment during a heist, must make her way through a secretive research facility. With help from her friends, she investigates the lab and searches for a way home.
The central ability lets Mittens split into two cats that can be controlled separately, then recombine. Use both positions to move through chambers, handle objects and energy, and navigate puzzles shaped by whether a cat is being observed.
New mechanics and areas expand the puzzles as you progress, while hidden rooms, collectibles, and documents reward exploring the facility. Play alone or in local co-op, and unlock options to customize the cats’ appearance.
Players often enjoy figuring out the split-cat puzzles, especially as new mechanics are introduced, and describe the challenge as satisfying without being punishing. Many also appreciate Mittens and the supporting characters, the humor, music, and rewards for exploring. Some reviewers find the puzzles too easy or repetitive, and others mention finicky jumping or technical problems.

Amidst a heist gone wrong, Mittens — the world's greatest (and most literal) cat burglar — finds herself caught in a quantum experiment, and gains incredible powers.
With the help of her friends and some new quantum tricks up her sleeve, Mittens must puzzle her way through the secretive research facility, uncover the truth, and make it home before breakfast.

The game is based around a central quantum mechanic — at the press of a button Mittens can split into two cats, who can each be controlled to solve puzzles and cause trouble.
The quantum superstate obeys Heisenberg's Uncertainty Principle - when nobody is looking, Mittens could be in either location. If she’s observed however, things get theoretical…
🚪 Pass through doors (that could theoretically have opened).
🚓 Avoid security detection (you can’t see what doesn’t exist).
🧵 Quantum mechanics plus cats. No strings attached!

Take a break from theoretical physics with some experimental fashion. Join the catwalk with plenty of strangely charming customisation options to unlock - each applicable to either quantum position.
Use your powers to access the inaccessible, evade the inevitable, and heist the unheistable to become Schrodinger's Cat Burglar!

A host of cat-splitting puzzles, sending items and energy across theoretical spacetime and back again in time for breakfast!
Play dress-up and choose custom hats, cat breeds, accessories and of course - level of cat chonkiness.
Have a friend join at any time in drop-in/out local coop, also compatible with Steam Remote Play Together.
What is this shady facility researching? What are the pest-control robots protecting? And who is this mysterious Shadow Cat…?
Hidden areas, sneaky mouse-bots and tricky quantum shards for the more advanced puzzle fans out there – or if you just want to knock coffee off desks, you can do that too…
