Great game. To balance out the overwhelming demand for more slots, I think that the 4 slot limit is great. It's limiting in a good way. As for suggestions, I had one idea. What if, every time you added a baby to the game, the method to unlocking it is a secret. Like, don't even give a hint that it's in the game. It would lead to avid fans searching for random things to do, and then sharing that answer with other people. I think it'd be a cool thing for people in the community to theorize about, wondering how many hidden babies are out there. Kind of like what is currently in the game for the brown ritual, but more likely to occur naturally. For example, you put dark bum in the game and the way to unlock him is to let 500 points worth of hearts despawn. No hints, just let people make their own discoveries and share the findings. I think it'd be fun.
