I played Six Cats Under as part of a "3 free random games" video - I also played Cats and Wires, as well as Goodbye Doggy.
I really enjoyed playing it! I thought the idea of the lady making sure her cats were okay was really sweet. The art style was cosy, the gameplay was good and I liked the puzzles. The story was a bit sad in the beginning - I have 6 cat's myself and I would hate for something to happen to them to it got me a bit in my feels... But I loved the game!
