I have.
It's... odd. Kinda cool, if vaguely depressing. (Wife: Cold, sick, hungry. Son: Cold, sick, hungry... etc)
The awkward controls combined with a time limit pretty much kill it for me though.
The 'highlight discrepancy" function in particular is annoying as hell. For example, in order to point out that someone is missing a document, you have to grab the rule book, flip through to the right page, click where it says "Must have document X", then click on the empty desk. All on a timer without keyboard shortcuts. Couldn't you just click the desk and be done with it?
If nothing else, it made me sympathize with bureaucrats a lot more:
"Why oh why can you motherfuckers not make sure your own documents are up to date?! Also, I swear to God, the next one of you who fails to provide an entry ticket straight away is getting denied on general principles. Also-also, I loath those passports that don't have the name of the country on them and you have to compare the symbol on the front. Fuck those things, fuck 'em with a rusty gardening fork."
