akeiler: For me the game stays german even with a full english Windows 10 and the region set to UK - this needs to be fixed as I surely won't play it in german.
Strange thing is that the game starts with an english "Begin" button, displays the message "loading languages" and then switches to german.
Yup. After playing the game a few rounds, I noticed that my version isn't actually german, as I thought at first, but it's a silly mix-up of english and german. Changing the system language didn't do anything, but that's besides the point, as I'll not bother with switching the system-language for a single game all the damn time. Whoever thought that this is a viable way to handle the language setting of the game, is an idiot.
