Game plays better with a controller, practically necessary, but only black boxes show in place of button prompts, tried to contact gog for a refund, they did not refund me and I was told that Nordic is aware of the issue, however forums show post as far back as January 2016 saying this is a problem and Nordic has done nothing . Steam version does not have this problem which means there is a patch that fixes it. Gog is of no support and just directed me to contact Nordic. They haven't released a patch since late November which is the patch that started the problem. That's 7 months without support and I am expected to believe that they will suddenly tend to the problem. I played the original version on 360, its a good game but avoid this version until they fix it. If they ever do, or buy it on Steam.
