Thank You! It is great to have an up-to-date version on GOG.

I've played the game a few hours recently and found something odd, though.
It seems that I cannot unlock any achievements, despite other people in my friends list having gotten them a few months ago. I've defeated several bosses so far and definitely performed some of the tasks outlined in the descriptions.
Is it possible this might be a minor issue with the current version here on GOG?

Little late to the party, brosky. But I just wanted to say I'm really sad what I heard from 505 support. There is a known v-sync issue that I have been reporting. Easily fixable. with alt-tab....but they say they aren't going to fix it. I guess that would be up to you. Great game, it just desyncs as soon as the 505 logo loads. You have to alt-tab to get v-sync back. Those cinematic type cut scenes also d-sync it.
