You are Sulphur Nimbus, a hippogriff who gets stuck on a cursed island during a sidequest gone wrong. Collect magical blobs, fight weird monsters, and get lost in the depths of the earth. You'll be able to fly wherever you want, but you're a horsebird so it won't be easy. As you dive deeper into the island's underground caverns, you must learn to manage your momentum with increasing care and precision. Sulphur Nimbus: Hel's Elixir takes inspiration from momentum-based platformers, six-degrees-of-freedom games, action adventures and collectathons.
