v0.1.9: Final itch build

I'm adding a limit to the number of cat you can have, just like the upcoming steam demo.

The itch io version will have a large different from the steam version. This build will be a more "pure" desktop pet vibe, while the steam build will have some idle game aspect and proper game progression, basically more contents in general.

It will also be the last build on itch io, and will probably not be updated anymore.
