Yeah Europe, Windows 10.
Thanks for your quick reply! I have found the issue thanks to your feedback: it's a localization error because of how American/European decimals are structured. I had a similar issue with my previous game STRIP Battle Action Cards, so luckily I can upload a new build within a few days with a fix for you. I'll make a note to European players for now that it may be unplayable for a few days until then.
