I've already played the entirety of Mary Skelter: Nightmares, twice actually if you count the remake included with 2, when I played this standalone version I did so on steam, where it would crash every freaking hour, honestly not so bad so long as you save often which I did but still plenty annoying, so thank god the GOG version doesn't crash, it feels amazing roaming the halls of jail without having to put down rabbit hole every 10 minutes just to be safe, the only downside is the lack of controller support, but you can probably find a workaround via remapping tools. Thank god it doesn't crash.
