Gameplay
The game is a 3D platformer akin to games such as Super Mario 64 and Banjo-Kazooie. However, the difference for this game is that it focuses on traveling from point A to point B. Levels will also have hidden collectables that unlock extras such as clips from the show, concept art and bonus costumes for Hilda.

Certain levels will also have the player control the Raven in his thunderbird form. When played, the level will switch to gameplay similar to the NiGHTS series.
