Very great game! fun art style, and I like that the synth almost wobbles like a "meow".
on another note, I have to report a bug where I got softlocked in the game somehow, conversation was finished with grandma and the box didn't say "Enter Living World" as it was supposed to, I probably messed it up by interacting with the evidence before the grandma, well I don't know, that's just my guess.
another tiny thing is the ceiling doesn't have collision, not game breaking though as the bounds prevent the cat from leaving the game world.
overall fun experience, will certainly come back at a later time and complete the full thing!
edit: uploaded a picture to explain the issue in case you wanted to fix it
