About
GAME LENGTH ESTIMATION :
Around 9-12 hours to complete the story, more to find all collectables.

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…

Have been loosely watching the game since launch, and knew that it would be a blast to play together with my sister. I was wrong. Turns out it is even better, because the game lets us play out cat brain to our hearts content while also giving amazing puzzles. We finished the first section and felt disheartened because we thought we'd somehow sped our way through everything. We were once again very, very wrong as there is still a lot of game left to go.
Cats, good puzzles and logic, and cute story bits. What's not to love?
Feels like an inferior portal game, having lots of hope and gripes, but its a tough call to give this a negative rating. The game is just too easy, solutions to puzzles are pretty obvious and the rest is just execution. I spent 4 hours immediatly cracking puzzles with bonus objectives and only got stuck for a minute once. A lot of it is just backtracking. Executions of solved puzzles also should not take this long, its downtime to just bore your brain. The devs were clearly afraid to make puzzles difficult and thats sad. Still the game has the potential to create very engaging puzzles and I want to see it realized, it feels like a rough diamond that needs some aggressive cutting to shine. The bigger offender is the writing, its too much and its not funny. Im certainly not reading some logs in a menu that have no relevant information beyond some cartoonish story flair. The antagonist AI character is offensively boring compared to the likes of Glados or Wheatly, who seemed clear inspirations. Just cut the dialog if you cant manage to write good one. Literally most of the advertised appeal is "haha cat funny", which is not enough to replace good writing. I also have no idea why they even attempted to shoehorn coop into puzzles designed for a single player, it makes no sense. Of the person will come up with the full solution and the other will just need to move one cat around (boring). Portal 2 coop was very ambitious and required both players to act indepently, with sometimes challenging navigation. It was designed for two brains and sometimes gave you slapstick situations from gameplay. This game does none of that. Also dont care about gathering coins for cosmetics. The reward is solving a difficult puzzle, not some cheap reward coins. Players would kill robo-mice for the fun of it, just cut the reward currency that kills intrinsic motivation. So while i would love exactly this kind of challenging puzzle game and all the pieces are there, they somehow missed the mark.
Wowowowow, I really don't know what to say. I've been following this project for around half a year and eventually played the demo. I loved the demo so I went ahead and bought the game. And I must say that this game exceeded all my expectations. The lore is very good and well written, the graphics look really nice, the sound design is fantastic, the level design is phenomenal. Everything about this just makes it an instabuy for me. 9.5/10, definitely gonna 100% soon!?
A game I truly adore, and it's very likely going to end up as my personal GOTY. I adore this game to bits and hope more people get the chance to play it, and I hope it does well. I've tried out both Mouse & Keyboard as well as a controller (Specifically the 8bitdo Ultimate 2c Wired) and they both work great, honestly! The default bindings are solid. I think most people will naturally slightly prefer a controller (like the game suggests on startup) because of the difference of movement between having, say, WASD for 8 cardinal directions vs. a typical controller's full 360 degrees of movement, but the game is more than playable with either option. The puzzles are great (including the optional extra collectables, like the chests), music is great, I love that the environmental design. I love Mittens and Susans' designs and characters, I love the mechanics, I can keep going. The game runs flawlessly, though with my setup that's to be expected. Loading times are very fast as is the time it takes to both start-up the game and officially begin playing, as well as when you're finished with a session for the night and wish to close the game, to boot The game as a whole is very 'plug 'n play' if you so wish, but there are a large amount of options to change controls and tweak other accessibility settings as one likes. There's a lot of customization that continues to broaden in options as you play the game. I truly have nothing bad to say about this title, only that I wish I picked it up sooner. I think a game like this could do really well on the Switch if given the opportunity. The joycons would be a natural fit for both singleplayer and co-op modes.
Phenomenal co-op puzzler. Can't wait for what the team comes up with next.
I played the game back before it came out fully in the demo. It was so much fun being able to go throughout the levels and find every small thing in the game that I could mess with. After the game came out and I was able to play through it fully. I can say this game is 100% worth dumping your time into, I still want to go back and explore the rest of the game, because the levels are designed in a way that makes it nice to go back to each level without having to walk the entire way back to find the small things. The game also has such a amazing story, that I can say is 100% worth it to read through and listen to everything. Plus the cats are cute.
after 15 hours, i finally finished- this game is an absolute joy to play [strike]even if you're not scientifically inclined.[/strike] it somehow managed to strike the balance between challenging and heartwarming, and did both flawlessly. the demo truly doesn't do it justice [strike][in a good way, i promise xD][/strike] and i know i'll definitely be replaying it more in the future. might need to let my brain restore itself from soup mode first though LOL [spoiler]that cliffhanger though... y'all are ♥♥♥♥♥♥ evilll /light-hearted[/spoiler] can't wait to see what our beloved gang get up to in the future :]
Very cosy and interesting game with neat option for one player to solve puzzle if another one is stuck (saves marriages, believe me). Haven't finished it as of time of writing this, so expect at least 15 hours of cooperative gameplay for it's money
So usually I don't write reviews like these but this time it's really different. This game is honestly worth getting if you are into puzzle games, they are good kind of challenging and the lore is also quite good. Unfortunately at the time of writing this, I haven't touched the co-op yet but I would be happy to try that out. When I stumbled upon the game on Instagram, I couldn't pass this one up. It was worth the wait and the purchase at release. Can't wait to see a sequel or a DLC from this studio, I plan on following their developments a little better now.
