Midway through making the game, PC version developers KnowWonder had to do a hard reset and completely restart their development of the game after the lore restrictions employed by Rowling made their original game uninteresting and a "glorified walking simulator", as they put it. Specifically, much of the KnowWonder's ideas had to be abandoned or worked around because many of the spells they wanted to adapt to gameplay they couldn't because first year Hogwarts students didn't have access to such abilities.

Going back to the drawing board caused the redone game to be rushed and the developers to experience crunch, but despite this, they still "found their groove" that helped them create the final game. The team also greatly understood Rowling's strict demand as they were huge fans of the source material.

Rowling also helped KnowWonder by creating a new spell for the team which didn't appear in her novels or on-screen before: Flipendo, a movement spell. Developer Christo Vuchetich opines that Rowling knew what went into making a game by giving his team vague and simple descriptions for the list of first year spells (i.e. "Flipendo moves things").
