Thor the God of Thunder

We are in Scandinavia. It is Ragnarök, the final battle of the Gods, the end of the world according to the Vikings. Thor, the god of Thunder, is fighting against Jormungand, a gigantic serpent. But Thor is at a disadvantage: he is fighting without his hammer, which has been stolen and hidden in a temple by Loki, the god of mischief. Loki has managed to cast an ancient spell that allowed him to move Thor's hammer and lock it in an enchanted place. According to the prophecy, without his weapon, Thor cannot win his battle. Can you retrieve it? Enter the temple and travel between the world of humans and that of the gods, in order to lift all the spells cast by Loki and recover Mjöllnir, Thor's Hammer.
