Reviews

“Schrodinger’s Cat Burglar was one of the booths that was so popular that I was forced to circle back multiple times before I was able to have a proper chat with Martin, the lead developer on this cute quantum physics-infused puzzle game.”
Player2

“Worrying what your pet might be up to while you’re away has never been so hilarious.”
GamesHub

“It’s all sorts of cheeky with puzzles that really require you to stop and think, and the mechanics of ‘observed’ and ‘theoretical’ are cool as hell.”
Kotaku

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!

🤫 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…
