>>43480245>What are apricornsYou meet a man later on who can turn them into different kinds of pokeballs. Nothing super useful though.
>Will the game become harderGen 2 has a bad problem with level jumps. Expect to be underleveled at many points of the game, even if you fight every trainer along the way. Fighting every wild mon you encounter may solve this a bit, but then you run out of pp moves.
I hope you like grind sessions. (Hgss is the only game where grinding is a problem, so don't go into the other games with this mindset)
>General tipsTalk to everyone, some give you neat items and in some cases they can give you pokemon. Don't feel bad if you have to switch a mon out because it stopped being useful, some mons are good at the start but not much more.
