Any age settings, max food and nesting material, genes unlocked
start with a randomized starter pair and breed them until you have 3 compatible pairs of siblings (or more if you want). This is where the challenge begins.
Each pair must breed until they have 2 compatible offspring
No mutation menu
No inviting wanderers unless a pair doesn't have compatible successors
The goal is to see how their descendants look after 20 generations (you can have a lower goal if you want)
