The Yuri Game Jam first started in 2015 and continues each year. The jam itself lasts for two months and looks for games focusing on relationships between women.
This game jam theme allows for representation of all kinds of female-identified characters. All manner of relationships can be showcased as well, such as presenting an aromantic or bisexual romance.
Is two months not enough time to create your yuri title? Feel free to submit an unfinished game or demo! Check this link on itch.io to join or watch for submissions.
