What the heck? Unsuspecting, you open the front door wide to find a box containing … a half-dead cat!? Using smart puzzle skills and clever outside-the-box thinking, you can help Kitty Q to escape her peculiar quantum superposition!
Don’t worry—Anna is there to help you. She’s the great-granddaughter of the world-famous physicist and Nobel Prize winner, Erwin Schrödinger. She will help you guide Kitty Q out of the crazy quantum world. Inside the box, everything follows its own curious rules. It really is an odd world here as Anna explains, but together you get to explore her great-grandfather Erwin Schrödinger’s specialist subject: quantum physics. Every puzzle in the game refers to observations, experiments, or phenomena from this totally unbelievable field of science. It’s a whole new world to discover!
So, you’ll get to know…
· why some tiny particles absolutely contradict all the rules at times,
· which letter will make your math teacher sweat,
· how you look in a selfie with a self-styled, half-dead cat!
In Kitty Q, you will discover more than 20 scientific facts about quantum physics that will amaze everyone. 
The quantum adventure Kitty Q has been developed in collaboration with the Cluster of Excellence* ct.qmat and is completely free and without ads or in-app purchases—thanks to the funding of the German Federal Ministry of Education and Research as part of the initiative ‘Research in Germany’.
*A Cluster of Excellence is a team of outstanding scientists who explore new challenges and unsolved puzzles. The answers that they find could have a crucial impact on our lives in the future. For ct.qmat, quantum physics takes center stage.

L’ami oc does not disappoint yet again! Keep up the great things you beautiful Germans do, I’ll keep getting your apps, they’re the most quality things in my phone!

My only real gripe with this game is when I played it a second time and chose for the cat to be dead, I really wanted a horribly depressing ending where we peek into the box and see a decomposing lifeless motionless animal with flies swarming around it. It’s cute and all that that didn’t happen but a bit of a let down. I guess I’m just a twisted person.

Great game, for real. I appreciate the app that connects the puzzles to real quantum concepts it was fun to read and elevated the experience for me

PART 2!!!

This game had gone above and beyond my standards of what I thought it would be like for a free game. From the nice graphics, interactions, and all around game play, not to mention how creative and eye catching/interesting it is. Definitely awesome! Please create a part 2, sequel/prequel or maybe even an all around new game that’s similar to this and it would be nice if it had more in it to where we can play for longer. For a new game like this, I would definitely pay a nice price for this. Super surprised that it’s free. Again, definitely an awesome game :)

A wonderful game

From what i’ve played so far of this game, it’s honestly great. The puzzles are challenging, but not impossible, which most puzzle games struggle with. I also really like how interactive it is, like how you can go through the characters phone and look through the kittypedia. I will update my review soon once i have completed the game, but it looks great so far, keep up the good work. Overall, 4.7 stars.

Sincerely, Crystal Corpses.
