About this gameFull description from Steam
Flats Full of Cats is a cozy hidden object game where you explore adorable apartments packed with feline friends! Discover three themed apartments inspired by science, mystery, and adventure! Join a policeman, a paleontologist, and a scientist in their cat-filled homes — each packed with unique details, hidden clues, and plenty of furry friends waiting to be found. Search every corner, find all the hidden cats, and enjoy charming hand-drawn visuals and relaxing music. It’s the purrfect game for cat lovers and anyone looking for a wholesome, stress-free experience. What is Flats Full of Cats? Flats Full of Cats is a building not bound by time or space (or even logic!); it lets us explore fun and creative ideas that wouldn’t have enough content to become full standalone games. Each floor is a self-contained episode with its own story and a quest that connects the three apartments it holds. Flats Full of Cats includes three play modes: Normal Mode features 300 cats with detailed designs that match the theme of each floor. Expert Mode features 300 minimalist cats designed for players with sharp eyes and plenty of experience. Time Attack Mode is a replay-oriented mode that generates a mix of 100 cats and records how long you take in each apartment – and if you’re not in the mood for this mode, that’s perfectly fine; you don’t need to play it to complete the story. As cats, we always appreciate free treats, so the first floor is free to play! And since every cat deserves to explore at their own pace, you can simply purchase the themes you find most interesting and embark on a feline adventure filled with magic, laughter, and inspiration!
