I don't know if it's just me but the lasso wouldn't spin when i was moving. I tried many times but couldn't catch any employee, they move too fast and I couldn't throw the lasso far enough or accurately enough. But catching 0 employee means they could go home get some rest so it's a win by my book.
While adding a lose condition seemed a good idea at first, I would advise against using a timer (except in some specific cases like race games), I think it is better to pick something that suits the gameplay, for example here you could give a limited number of throw (more lasso would exceed the company's budget or something). But in a slow paced game, a timer is usually not the best choice and it can negatively affect the gameplay.
