Cool stuff, I enjoyed it! After I completed the first day I was a bit worried the gameplay wouldn't be engaging enough, but once things get rolling it's heart-racing stuff - especially the line from the glutton that's begins with 'Not...'. Much more relaxing that Papers Please, though (thank God - loved that game, but oh boy, the stress). The last day was hilarious with the cooks trying to hoodwink you bigtime.
My day job is also highly analytical so things went mostly to plan except that one vanilla cake that ended up with vinegar in it (lol), and a couple of expired ingredients. Also had to convert the expiry dates in my head from MM/DD to DD/MM which added a lil extra challenge. In the end I made out with $340 of ill-gotten gains (well $240 I suppose as you begin with 100 bux don't you). Restaurant work is a tough gig even while you're committing fraud.
Does the 'load game' button do anything different to 'new game'? I didn't want to try exiting the game early in case game state wasn't saved.
Well done on the UI. Only things I can think of as improvements: maybe allow rejection of orders before the cook finishes their blathering - though it's kind of nice to have the breather once you spot a mistake. And as mentioned above it'd be nice to have a DD/MM/YYYY option (or even YYYY/MM/DD for the 100% sensible date format users) though I dunno how easy that localisation feature would be.
Oh yeah, one other random thing. The typewriter noise really reminded me of the David Crane Ghostbusters game from 1984...
