Moran's works often incorporate elements of surrealism, dream logic, and philosophical inquiry. She explores the nature of reality, identity, and the human condition through fantastical and often unsettling narratives.

A strong theme running across multiple games, particularly in "Don't Rest Your Head", centers around mental health, insomnia, and the effects of chronic exhaustion on perception and sanity.

Moran is known for designing unconventional and innovative game mechanics that emphasize narrative and character development over traditional combat or skill-based systems. "The Shab-al-Hiri Roach"'s 'Mannerisms' and "Don't Rest Your Head"'s dice pool system are notable examples.

Emphasis on the character's internal states, motivations, and relationships is always present. Her games give players space for self-expression and improvisation.
