An interactive horror story which is a retelling of The Whisperer in Darkness, a short story by H.P. Lovecraft. There isn’t much in the way of gameplay, and it’s more of an atmospheric way to experience a horror novel (with really nice art, and music).
It was made for the Public Game Jam in 2014, and all the assets are open source and free to use. You can download them, as well as the game from itch.io. It’s available for PC, and is currently being rewritten for Mac and Linux.
