[FULL] Forever's End: Episode One

[Jazz]

This game is great! I've been playing for tree days now and I' m still enjoying the story and the whole atmosphere.
But I' ve got some questions: Is it possible to return to some of the areas later in the game? I' ve missed to catch some of the monsters so I couldn't get the reward...
And I can't find the special spirit in the desert that leads me to a treasure. I'm quiet sure that I' ve tried all possible ways... where is it hidden?
