Thank you so much for your comment! I'm really glad you found the game fun.
You're absolutely right to notice that nature inheritance feels off. Let me explain how it currently works: 40% chance to inherit nature from parent 1, 40% from parent 2, and 20% completely random. That's why even two creatures with the same nature often produce offspring with a different nature — the random 20% can override things, and the 40/40 split doesn't guarantee the same nature even when both parents match.
I agree this isn't ideal, and I hope to rework the inheritance system in a future update to make it more logical and predictable.
Your feedback is really helpful!
By the way, what part of the game did you enjoy the most? I'd love to know.
