Mattie is currently an independent, medium-agnostic game designer. There are many philosophies going into her work; for one, she makes games on accessible platforms that people without programming knowledge or reserves of disposable income can develop on. This includes programs like RPG Maker VX, Twine, and also analogue games. Her games test the edges of what is thought possible with game design and aim to be inclusive on multiple levels. She also focuses on narrative design and experiments with narrative and experience in games. Mattie seeks independent contracting, collaborations, and design roles on larger teams.
