FAQ

How do I heal my Pokemon?
They will automatically be healed to full if you die, a PokeNurse will spawn to heal them at no cost (no prerequisite for spawn), and the Merchant sells various types of potions to heal them too. Each new type of potion is unlocked by defeating bosses.

Where do I get Pokeballs?
The Merchant sells Pokeballs, more types become available when bosses are defeated.
