Gilgenbach revealed Neverending Nighmares last month. It's a radical departure from his previous title which was a rhythm-shooter. Gilgenbach describes Neverending Nightmares as a highly personal horror game that is a manifestation of his own personal issues with depression and OCD. Retro/Grade was a critical success, but a "financial failure" as Gilgenbach refers to it, and it caused him to revert into his depression, and inspire him to begin working on the game.
It's a horror-puzzle game with a focus on atmosphere. The player controls Adam who must figure out what is real, and what is a product of his subconsciousness as he continually wakes up in constatnly shifting realities.
You can check out the pitch video for the game below as well as screenshots from the game in the gallery. As a warning, there is some disturbing imagery in both the images and the video. You can check out the game's announcement trailer here. To check out the game's Kickstarter and possibly pledge some money, head here. Matt Gilgenbach will also be on hand in the Indie Megabooth at PAX this week to show off the game.
