A pretty good game, but unfortunately has bad lag, particularly in the graveyard area. It's probably that spotlight flare effect doing it. Playing on lowest quality.
That makes the Cacturne quest absolutely miserable. Aside from that area the game was manageable, though I've had others tell me it lags up unplayably for them even at the very start.
Charmander is the best starting choice. Other than that you'll want a Dratini as soon as you can get one and a Wingull is quite good early on but you'll probably drop it later in the game.
Once you get an Onix he will probably be your go-to Pokemon.
Got a Lapras. Ditched him for Dratini even though I maybe should have kept Lapras. Doesn't matter that much as they're very similar except Lapras is extremely rare and slightly better book stats, but didn't notice much difference in actual use.
You also definitely want a Butterfree at some point.
And you probably don't want to drop the Girafarig as I don't think you can get another.
