This is an unpaid, remote collaboration for Project Mercy, an independent dark science-fantasy roguelite currently in development at Memoria Works.

Our current goal is to build a high-quality playable demo that we can use to pursue external funding and investment for full development, with crowdfunding also being considered as an alternative route.

You will work closely with Design, Programming, Level Design, Narrative, Production and other departments, helping turn the established vision for Project Mercy into clear, practical and testable gameplay systems.

Our international team includes developers and artists with professional AAA and broader industry experience. The goal of the demo is to present a strong representation of Project Mercy and use it to pursue funding for full development.
