The story isn't nearly complete yet. Currently none of the gyms work and you can only get up to Lavender Town. Hopefully within a few releases FreezeWarp will have working gyms and stuff finished. For now, though, you can only really adopt, trade and fight other people, and explore the map up to Lavender Town.

The next release, hopefully in September but might be October, will:
1. Fix all gyms, allowing you to battle them (or the first four that you can access anyway).
2. Allow access up to Celadon (Saffron and Fushcia+ won't be accessible yet).
3. Allow far more Pokémon to be catchable in the wild.
4. Add a breeding center.
5. Add the Celadon Gamecorner and possibly some fun events for it.
