I like the art style and it's a great idea, living as a cat when your owner is dead. I would love to see more of it, explore more of the house, do more things, see what the crafting is all about.
And what the cat does to nana is exactly what a cat would do the moment you die.
The music is nice and relaxing.
Although its very easy to fall out of the level if you walk forward.
I'm guessing after 20 days the granddaughter is meant to turn up only to find nana dead, with all of her clothes turned into calls of yarn and the cat licking its paws.
Good work.
