Hey ifo - we'll definitely have a Linux version available, whether it's DRM free is the question tho. We plan to release on GOG, and sent them a test build last week. Just waiting on their approval before we can confirm ;)
I've just pre-ordered a digital copy of the 13th doll , it said I would receive a paypal receipt to my email address but I've had nothing and also I can't find out how to contact you to see if there is an update as to the games release date , this is why i'm asking on here.
