Hi!
I'm missing something because I don't know how to play : I'm in the first room, and can move, use my sword, cast fireballs and use the inventory to select some crystals but I'm stuck. I've tried to use my sword or cast fireballs to the altar or the doors, with or without a colored crystal set in the inventory, tried every key of my keyboard in front of everything and yet nothing changed. Can someone give me a clue of what to do please?
Thanks!
