Does anyone have any idea of how to get into the Floating Continent? I'm at the jungle entrance but there's an unbreakable door blocking my passage. I tried shooting with Geddy and Alphonse and throwing them, but nothing seems to work. I'll explore more tomorrow, loving the game, but I'm sad to be stumped this early in it.

[EDIT] Turns out I just wasn't aiming well enough with Alphonse. You can ignore this thread.
