Oh I didn't know she was a solo dev that's more impressive! I always like to say thanks to the dev(s) plural just incase, as a way to show my gratitude for anyone behind the scenes of a project, no matter the size of their contribution. Also dev (developer) can be used interchangeably with creator regardless of genre ☺️
