My name is Cosmo D.  Before I started making games, I was performing around New York as a cellist. This led me to work in audio engineering, music writing for dance clubs, TV commercials and more. I’ve generally tried to stay open to a wide variety of creative avenues.

This openness led me to experimenting in game design around 2013. I’ve been building on my craft since then. To date, I’ve released four games. These include “Off-Peak,” “The Norwood Suite,” and “Tales From Off-Peak City.” My most recent release, “Betrayal At Club Low”, won the Seamus McNally Grand Prize in 2023.

My games aim to provide intriguing stories, satisfying gameplay and a vibe rooted in my home city, NYC.
