Evaluation

Schrodinger's Cat Burglar launched on May 21, 2026 and has since received active post-launch support from developer Abandoned Sheep. The major content addition came on August 5, 2026 with the "Bonus Puzzles" update, which added a new Experimental Department area containing three new puzzle levels unlocked progressively through the story. This was followed by a series of feature patches through September 2026 — adding photo mode, an engine upgrade to Unity 6.3, direction signs, HDR support, and various quality-of-life improvements. The developer's most recent post, dated September 28, 2026 and tagged as a development status update, states: "OK, this really is the last update for a while here." This closely follows an earlier September 22, 2026 patch note that similarly said "Last update for a while here." Two back-to-back developer statements — the second explicitly reinforcing the first — indicate the developer considers the current state of the game their concluding update pass. No future content has been announced, and no unreleased DLC exists on the store. The only DLC listed (a Supporter Pack and a Soundtrack) both released on launch day, May 21, 2026. With the last meaningful content addition shipped on August 5, 2026, no outstanding commitments, and the developer explicitly signalling they are done updating for now, the game is complete.

About this game

QUANTUM POWERS

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.

FUN PUZZLES

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.

BUT THERE’S A TWIST

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!

CUTE CATS

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 QUANTUM ADVENTURE THAT'S ONE OF A KIND!

KEY FEATURES:

🧬 Brain-Teasering Puzzles

A host of cat-splitting puzzles, sending items and energy across theoretical spacetime and back again in time for breakfast! 

🎨 Full Customisation

Play dress-up and choose custom hats, cat breeds, accessories and of course - level of cat chonkiness. 

👥 Play With a Friend

Have a friend join at any time in drop-in/out local coop, also compatible with Steam Remote Play Together. 

🤫 Unravel The Secrets of The Lab

What is this shady facility researching? What are the pest-control robots protecting? And who is this mysterious Shadow Cat…? 

🏆 Expanded Gameplay

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…
