coming from bee swarm i respect a good progression curve, and PS99 has one. hatch pets, merge duplicates up, enchant for stats, and work toward huge and titanic pets, with a big collection index giving you long term goals and events keeping new content flowing. where it drops a star for me is how much of the top end is pure RNG and shop pressure, the best pets are a luck and wallet wall more than a planning wall, which bee swarm mostly avoids. still, if you farm smart, put your coins and keys into the best value eggs for the current meta instead of chasing every shiny, theres a genuinely satisfying grind here. 4. good farming game, just keep your expectations honest about the luck gates.
