I got to Tuesday, week 5. I feel like it's building up to something, but the loop was starting to feel a little tedious, so I saved my progress and may continue again later.
I like the idea, I dig the background changing to match the narrative, and definitely appreciate a functioning save feature! The tediousness of the job actually kind of fits for the theme of the jam; however, for a more engaging game, I'd definitely want something more. Part of what Papers Please so appealing is that you got glimpses of how your choices were effecting the people you were interacting with, and I think Tollbooth could benefit from something like that. Also adding player consequences would be good (docked pay for mistakes, bills that have to be paid to keep your family healthy, etc.) .
Overall, I think this is a fine submission for the Jam. It certainly fits the theme, and is a solid base for a game!
