it's great as a piece of historical intrigue, but as others have said here, some of it just does not hold up. Controls are a little clunky, and the story is fine but no longer nearly as interesting or surprising as it was back in 2008. Nowadays, you can't go to Steam without tripping over 3 indie puzzle platformers with better controls and story. I think the puzzle design probably still holds up, but i haven't played recently so i can't say for sure.
