I love the idea!
Fun concept, I like that unique workers have their own attributes that affect each run. I'd assume they could build something that will optimize the job scheduling for them :)
Only suggestions that come in mind is enlarging the text, especially in the help page, it's quite small and hard to follow (the coloring might have also helped that). Also scaling the speed of the game can be a nice add-on.
Regardless, loved it and that's super unique, well done :)
