I hinted at this in my Monthly Goals post  yesterday. Well, it's here quicker than I anticipated!

I'm now hosting a game Jam Titled DARK Serenity.
It's for games that dark vibe / atmosphere, but are NOT horror games. 
The official start date is the 20th of this month, but feel free to start before.
There is no official theme to adhere to, but there is a theme section for suggesting or discovering themes submitted by the community.
