Munin, Odin’s faithful raven, starts its journey through the nine realms of Yggdrasil to find its lost wings in a new 2D puzzle platformer (http://tinyurl.com/pfr5qmq) for Mac OS X, Windows, and Linux systems. It costs US$9.99.

Here’s how the game is described: “In Munin, players enter a fantastic world of the legends of the Norse gods, because the raven Munin is one of the two loyal messengers of Odin, the father of the gods. But due to a capricious prank by Loki, he has been transformed into a little human girl, and its feathers have been scattered across the nine worlds of Yggdrasil. The players’ task is to find the feathers and restore the raven to his true form.”
