Gave the new update a go... man. I am rusty to level 1. Took a few tries to finish it. Tried Level 2... very difficult. Got close but I must say it is real rough trying to deal the other workers compared to the office. Makes sense if I'm honest though navigating the responses is much trickier since I think one of them ended up sending more dudes than expected. Though dealing with a few don't change rates regardless of if you have clothes on, off, or directly going at it. Though there was a bug that I found. It is I think just a visual one regarding the gauge of progress. Basically even after finishing off a guy and going back to work with your clothes back on, it doesn't move from yellow. Speed returns to normal but the visual doesn't update until the next guy shows up.
I am not too sure what to suggest but I got an idea. What about a simple pair of trays with paper that is gradually going down? Like how people have stacks of paper in a tray for "in" and "out" when working in an office. With the basic visual of having the IN tray full at the start but gradually moving into the OUT tray with more stacking to the IN tray when the "co-workers" visit.
