Thank you so much!! :)
I appreciate the feedback about the elementals, that was indeed a flaw that I wasn't able to iron out for this... perhaps ecaroh could re-summon them? Hmm.. that could bypass obstacles with ease, though... I'll have to brainstorm this one!
As for the orbs - that was another quick last minute addition just to add a little side quest to the game. There's actually more than 4 easter eggs out beyond the horizon... But they currently don't serve any real purpose. I think if I expand the game, they will act like Mario's stars or Banjo & Kazooie jiggies, to unlock doors that require a certain amount!
