Wow thanks for the many comments! I do think if we were to continue this project, that we'd focus on the more chill/adorable path rather than the chaos path (though babies of all species are good at chaos!). From the credits there should be a button in the bottom left that allows returning to the main menu. But from the game scene there is no way to leave. This is what our marketing team calls a "retention strategy" and certainly not because we just forgot. Oops!
You're right that Mama currently can play with toys but not with kittens, she can only pick them up. The kittens do eventually wake up, I just confirmed, but it takes a long time. It is about 13x faster in bed. Goes to show what a good mattress can do for your sleep :)
Thanks again for playing!
