Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 1.29/day in the week to Aug 8 → 1.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About

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…

Great mind bending puzzles. Very cute cats. Favorite control input is the Meow button. The only real negative I can say is that I will need to wait for a sequel... I want more.
J'ai bien aimé le jeu, c'est énigmes sont sympa, les chats sont mignon, l'histoire est prenante.
Wow, this is a great little game from a small company. The story is very well told, it's got mystery, suspense, jokes, and an AI that is 'maybe' smarter than GlaDOS. Of course there are some similarities to Portal, as far as puzzles go. However, there are lots of NEW and different things that are quite unique only to this games puzzle solving. The areas are fun to explore, and the puzzles are not too difficult so that you can just enjoy this cute casual cat game at your own pace! Cause who doesn't love a cat game right? You can also enjoy playing co-op with your daughter, wife, husband, brother, cat, or your creepy neighbor Jerry even! Just don't play it with your dog. Highly Recommended!! Give this developer some love, they really did a great job on a very fun game! Double thumbs up from me!!

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.
Fantastic puzzle platformer. While I found some of the end game puzzles a bit too trivial compared to some of the ones you had to get to get there, it was a thoroughly enjoyable ride. Help save the world through Mittens!!
The game mechanics are so fun, the customization for the cats is so adorable, and it's such a fun game to play when you want something chill to relax with.
Cute cats, fun gameplay and story based puzzles. Love it.
Quite a fun puzzle game. Fun story, good game mechanics, nice design. Cosmetics to dress up the cat in are a fun bonus and I'm so glad it's like the old days where it's all earned in-game instead of the game being riddled with microtransactions. Nothing that takes too long to solve, as most puzzles' solutions can be figured out with some trial and error. By that front I'd say difficulty is accessible, so long as you can get comfortable with the "aim then jump" mechanic. My only real complaint is that the demo makes going through the Separation Lab in the full version a relatively boring section because you've already done 2/3 of it once before.
so, neat tip for anyone with color 3d glasses, go to the player settings and set cat 1's color to the right lens and cat 2's color to the left lens to create a trippy visual effect that darkens each cat for each eye :3
One of the best puzzle games and probably the best puzzle game featuring a cat. The controls are pretty good but does take getting used to. It is a lot longer than I expected with some of the puzzles having quite a bit of complexity. There's a lot of theoretical physics, a lot of puns, and some terrible jokes. I haven't even done the bonus puzzles but I've played through the whole game. The demo gives you pretty thorough exposure to what you're going to experience in the game.
