We pushed an experimental patch on the main branch using latest Unity alpha version that should fix the Windows 7 issue, all Window 7 players should be able to play the Chapter III on the main branch but since it's an alpha version of Unity there may be unexpected new issues. Please report us any new issues that you find using this version, thanks.
Also the team is going to Gamescom, if any of you comes by please don't hesitate to say hi, we will be on the Indie Arena area
Also since we will be at Gamescom there will be no new patch during a week (we will be there 18 - 25 August), we will resume improving the game as soon as we get back!
Hope to see you there!
