 Haarsma's novels are accompanied by a free, online, role-playing game called "Rings of Orbis" which acts as a visual companion to the books and is set in the same universe.Players are sometimes required to use information from the books in order to solve puzzles and to unlock areas within the game.Pairing a video game with a novel for young readers, Haarsma says, “brings the book into their world, as opposed to going the other way around.” 

Haarsma and a team of artists also created many different alien races specifically for the game.
