Achievement Walkthrough:

Story related achievement. Can not be missed. You will free the fairy near the end of the game.

A full playthrough for this game is required. (not your average Xitilon)
It is challenging in areas and requires skill but checkpoints are very generous.
There are three missable achievements all covered very early in this guide.

Enjoy and good luck.
