Thanks for playing! I feel this game could have been better balanced in a million different ways, haha! SPOILERS: There are some secret interactions. People have a hunger meter that slowly ticks down and they can starve to death. They can eat bushes or bunnies. Bunnies and Slimes both eat bushes, too, though. If a bunny eats a bush and is satiated enough, it will spawn another bunny. Bushes and trees will spawn children every once in a while, too. Houses will spawn new people, though I think it spawns away from the house which makes it hard to tell.
