cool stuff, sorta reminds me of hitman with the stealing identity (/ stats in your case) of workers to progress to restricted spots. Should have a little tutorial message on the first guy telling players what to do (since was confusing had to read comments here to progress, maybe I didn't see there but more simple little tutorial nudges, like a text come-up could work for my case.
But nice stuff fits the theme well and the game-loop is fun for me! Sneaky little dude, I think it'd be cool/funny if we could also whack them (maybe like a little whack animation for stealing, sorta like hitman for stealing clothes, just some random fun thing to add)
