Munin casts its puzzle adventure in Norse mythology: the raven Munin, messenger to Odin, has been transformed by Loki into a mortal girl and must recover her feathers on a journey through Yggdrasil. That quest unfolds as a 2D side-scroller, but the terrain itself is the game’s defining puzzle tool. Rather than simply navigating a fixed route, players reshape parts of the world to make a way forward.
Rotating sections can turn walls into floors, connect pillars as bridges, or expose new passages. The consequences extend to objects and hazards: boulders and debris roll or fall, water and lava flow, and switches and other movable elements add complications. Norse runes point toward the lost feathers, giving the environmental rearrangement a clear goal. The challenge comes from working out how a change in orientation affects the route and the things moving through it.
The store describes nine worlds and 77 levels, presenting Munin as a sequence of designed puzzles rather than an open-ended or competitive format. The stated playtime is roughly seven hours, a useful indication of the campaign’s scale without changing its central appeal: making the landscape behave differently to reach what lies beyond it.
