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.

🤫 Unravel The Secrets of The Lab
