Passage: The initial idea for A Hat in Time was started by director Jonas Kærlev, who launched the project as an answer to his feeling of an ongoing shortage of 3D platformers, specifically developed by Nintendo. Some inspirations include Psychonauts, Paper Mario, Spyro the Dragon and Banjo-Kazooie. In an interview with Polygon, Kærlev revealed that he and Gears for Breakfast initially did not expect the Kickstarter success A Hat in Time eventually received. Kærlev thought that there would be little demand for the game due to Donkey Kong 64's effects on the genre, which he perceived as overwhelming the player with too much collecting. Development for the game started in August 2012 and was planned for a Q2 2013 release but has been significantly delayed. At the start of development, Kærlev was the sole developer of the game but over time the development grew into Gears for Breakfast, a team spanning four countries and entirely volunteer-based. Through the Kickstarter campaign the game surpassed the initial goal of $30,000 with a final total of $296,360. In July 2013, it was announced that the game had been greenlit for release via Steam. The soundtrack was mostly composed by Pascal Michael Stiefel, with several guest composers such as Grant Kirkhope contributing additional tracks to the game.
