could pull off a sweet pokeball adventure in which once inside an entire world opens up to check out, dependent on the ball type
regular pokeball might have grasslands & generally temperate biomes, more of like a hub world where practically everyone visits
gsball might open up to a massive chain of golden chambers that lead to other pokeballs
masterball could lead to the final area where once completed allows the player to leave the boundaries of the pokeballs
or just resets mini lol
