I use this site for as many games as possible, and I just recently solved an issue for Ori and the Blind Forest. I am running Windows 8.1, and the game has not been responding to me when I launch it. Sometimes it works when I restart the computer and launch the game before anything else. I just launched the game perfectly fine multiple times in a row with the game running in Windows 7 compatibility mode on. I was about to update the wiki page for this, but I have never done any wiki editing before. I do, however, love forums. Perhaps some other people could confirm this is a working fix for the problem and update the wiki page.
