Auto upgrading in Pet Simulator 99
Stronger pets break things faster, which earns more coins, which buys more upgrades — that's the progression loop in Pet Simulator 99. Managing rank-ups, enchants and evolutions by hand is fiddly. This script handles all of it, keeping your best pets ranked, enchanted and evolved so your damage keeps climbing.
It closes the loop on a hands-off setup: the auto farm script earns the materials, auto hatch supplies new pets, and auto upgrade turns them into a stronger team.
