The stretch goals the game managed to hit include Oculus Rift support, a commentary track, and a round of ice cream for the entire development crew. Yum!
It barely missed the $250K goal which would have brought downloadable content to the game, though this will probably still happen with other funding sources, and the fact that it failed to meet the goal by less than $1.7K.
Among the Sleep is due to be released this coming December 2013 for PC. An alpha build is currently available for download at the Kickstarter page here.
