ABSTRACT
A challenge is the essential unit of content in a level. A cadence is the progression of challenges explained by their relation to the standard challenge. Just as challenges add up into cadences, levels add up into skill themes. Skill themes in a composite game are the material embodiment of composite design. The safe spaces between challenges are the best way to figure out when a challenge begins and ends. Mutation challenges are important because not every single challenge can get more difficult or complex, or else many levels would become tiresome. A training-wheels challenge is designed to allow players to use new skills in a low-risk, easy-to-understand environment. The punctuating challenge is a kind of punctuation mark in the sentence of a cadence. Crossover challenges are important to a cadence because they arise out of the complement theme and tend to work with the skills already in play in the cadence, rather than merely punctuating them.
