I would have liked to see more interesting concepts like actually faking the passport or trying to sneak across the border. As it is, the game is mostly about stumbling across money to buy the correct passport with, then stumbling across the correct place to go.
I feel uncomfortable that unedited gameplay of Papers Please just plays at the end of the game, regardless of the context. It's plagarism. If you wanted to use Papers Please as a starting point, that's fine, but you can't just play footage of another game in yours.
