This is a great game, and I greatly enjoyed playing it. The story was very compelling, and the puzzles both interesting from a political or story standpoint, a humor standpoint, as well as pinpointed the best difficulty.
The game has one very crippling bug: occasionally options will not show up. This happened to me for the CORRECT option - twice. This was my second playthrough, so I remembered some of the puzzles' solutions. On Level 7, the second "if, then" needed was (spoilers) "If games should be compared similarly to film, then Australia is wrong to ban 18+ rated games. The option for "Australia is wrong to ban games" was not listed.
The same happened on the final level (which, by the way, is unskippable if you want to see the game's ending) wherein the options O and Not O were not shown. O is the answer, meaning I could not see the ending (not a big deal for me; I already know the ending, but knowing others cannot see it is... painful).
From the reviews below, this is a very common problem. The only thing that comes to mind is that the first time I played it I used Mozilla Firefox, while the second time I played it in Google Chrome, so it may be a browser issue. To those below with a similar problem, try using Firefox and see if that works.
