Very challenging! I love the game, It has such an awesome concept even if it's inspired! A horror game about somebody breaking in while you decrypt a file is awesome! And I spent many hours on it! If your up for working on the game anymore, could you create a nightmare difficulty or something? That would be so cool! I already got 3 stars, (Tell me if there is anymore, I love playing this!) and I would love a bigger challenge, I've already gotten very good at the game and I would love more content.
